Best ResponseYou've already chosen the best response.0for the given equation u got to make up a table for getting the points when u put x=0 in the given equation y value becomes 8 so , (0,8) is one of the points in the given straight line when u put y=0 in the given equation x value becomes 3 so, (3,0 ) is also one of the points in the given straight linedw:1358043164412:dw

Best ResponseYou've already chosen the best response.1The #7 had a mistype. \[y=\frac{ 3 }{ 5 }x4\] forgot the x.

Best ResponseYou've already chosen the best response.1Make sure when you draw the graphs, include the corresponding equation next to the line.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Okay, please specify. Are you stuck with getting the equations into intercept form or are you stuck with the sketching onto the graph?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Just to let you know I purposely haven't done #7 just to see where your mind is at. So if you're stuck with sketching we can go through #7 together as an example to make sure you understand.

Best ResponseYou've already chosen the best response.0#5 this is what I got when I did it: y 2= 2(x+3) 1  2 +2(1+3) 12=2(4) 12=8 (8,1)

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1okay, don't do that. That's a very slow way of sketching them. I got used to a method, where once you learn it completely, you can sketch the equation straight away in 10 seconds after looking at the equation.

MaeganR

Best ResponseYou've already chosen the best response.0how do you do that? and btw: is that correct anyways?

Azteck

Best ResponseYou've already chosen the best response.1Okay, do you know how to put the equations in to point intercept form?

Best ResponseYou've already chosen the best response.1y=mx+b where m is the gradient of the line, b is a constant.

MaeganR

Best ResponseYou've already chosen the best response.0y=mx+b is the formula, but i dont know how to do anything

Azteck

Best ResponseYou've already chosen the best response.1Do you know how to expand?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Ah, okay. Now that is something your teacher should have taught you before all this sketching and stuff.

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0my teacher just teaches everything in the book. in fact, we dont even use books. she just teaches us on the board and thats how we "LEARN".

Azteck

Best ResponseYou've already chosen the best response.1#5. y2=2(x+3) Expand this part: \[2(x+3)\]

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Don't you know how to remove the brackets?

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0is it also called distribute?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1I think so. Because I'm probably not from your country where you might teach differently. I meant paranthesis. I just call it brackets because it's maths and maths teachers don't care about the technical terms of that stuff.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Okay, If you expand/distribute \[2(x+3)\] Wouldn't you get \[2(x)+2(3)\]

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1and then you get \[2x+6\]

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0#5. y2=2(x+3) How do we do this?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1okay now, you have y2=2x+6

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1you want to put that into y=mx+b. Wouldn't you have to move the 2 to the LHS(Left Hand Side)?

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0wait how do you get the y+3 to be y2?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1You're looking at the second one. I'm at the first one.

MaeganR

Best ResponseYou've already chosen the best response.0nvm. sorrry i was looking at two different problems.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Okay, so put \[y2=2x+6\] into this form y=mx+b

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0because 6 would be b right?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1You're confusing me and we haven't started doing the other parts yet. Look at \[y−2=2x+6\]

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Now tell me what's the difference between this when you disregard the m's and b's in this equation: \[y=mx+b\]

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Okay. Have you played a game called Spot The Difference? You're trying to find the difference between that equation and the first one.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Come'on, this is the easiest form of mathematics at a standard level. You must know this in order to continue.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Okay, here's something you should know. Collect the like terms.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Do you know what collecting like terms is? Or have you not paid attention in class for a few years?

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0Ok. This is what ive done if it helps any.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1That's going to be hard to read don't you think. Okay, I'm asking you this sole question.

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0The teacher I have does not explain, she only gives us frayer diagrams to follow. This is why this is so confusing to me.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Do you understand the statement: "Collecting like terms"

MaeganR

Best ResponseYou've already chosen the best response.0is y=2x+8 anything to do with the answer?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Now, this is the easy part. That's what I think.

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0so now what do i do to get it to be pointslope form?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1All you have to do when sketching is find the x and y intercepts!

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1That is pointslope form?

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0ok so i can plug in like (1,1) and (3,3)?

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0y=2x+8 is slopeintercept form. I need it to be pointslope form which is yy1=m(xx1). Wait.. I think i know how to do that..

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Always when sketching lines, you start off by making x=0

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1so that means, you substitute x with 0!

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Anything multiplied by 0 always gives you zero!!

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Now you found that when you substitute x with 0 you get y=8

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1And your coordinates would be (0, 8). Because coordinates always look like this: (x, y)

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0i get it. y=2x+8 y=2(0)+8 y=0+8 y=8 !!! :D

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Yes!! Now that's called finding the yintercept. What would you do to find the xintercept? How would you eliminate y in order to find x?

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0whoa. whoa. whoa. hold up. let me think...

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0you would plug in 0 for y?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1WELL DONE! awesome job @MaeganR!

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1So what would you get for x?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1when you plug in 0 into y?

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.00=2x+8 is how you start right.?

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0so it would be (4,8) but how do you go up or down.?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1so now what would the coordinates of the xintercept be? Remember the coordinates take in the shape of this: (xvalue, yvalue)

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0wait. slope=2 2/1 up 2 over 1?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Forget the slope when sketching.

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0but htats what my teacher says to do? ):

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Haha, when you go up to senior years, all you do is put important features when sketching. The sketch doesn't need to be 00% perfect and to scale.

Best ResponseYou've already chosen the best response.0im in 7th grade advanced, so were taking a 9th grade class in 7th grade. legit, no joke

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Then if you're in 7th grade advanced, you should be smart as hell. Taking a 9th grade class when you're in 7th grade would require some form of intelligence and dexterity at mathematics. You should know allt his because this is 7th grade maths.

MaeganR

Best ResponseYou've already chosen the best response.0so (4,0) and (0,8)!?!?!?!?!

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Now run run a line along the two points

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1You don't need to be precise in your placement of the coordinates.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1but make sure the x and y intecept are on the x and y axis respectively.

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0but were not leaning 7th grade stuff. we wont learn 8th grade stuff either. its like 7th grade=9th grade 8thgrade=10th grade 9th grade=11th grade 10th grade=12th grade 11th+12th grade=college for free in high school. basically im skipping grades. its so confusing.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Why are you skipping grades with this limited knowledge of maths? If you keep going at this rate, you're on the road to failure.

MaeganR

Best ResponseYou've already chosen the best response.0yay. thank you so much. ive been so frustrated for a month because nobody would actually take the time to explain the whole thing to me in unbig scarey words. thank you so much. :)

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1No worries. I think keeping it simple and just using baby talk always makes more sense than sophisticated and complicated words.

MaeganR
 2 years ago
Best ResponseYou've already chosen the best response.0because i have to do this. theres no way out of the advanced program. once the school puts you in it without youre choice youre there, whether you fail or not.
