Best ResponseYou've already chosen the best response.0You need the form y = mx+b. So manipulate the equation to isolate Y.

Best ResponseYou've already chosen the best response.0and m would then be my answer>

Best ResponseYou've already chosen the best response.0Yes, you are looking for m.

Best ResponseYou've already chosen the best response.0practically ,  x's coefficient / y's coefficient so , 2/3

Best ResponseYou've already chosen the best response.0So I would first subtract the 2x to the other side, leaving 3y = 2x +6.

anonymous

Best ResponseYou've already chosen the best response.0Then you divide by 3 since 3y/3 would just leave you with y.

anonymous

Best ResponseYou've already chosen the best response.0divide both sides by 3 that is.

Best ResponseYou've already chosen the best response.0ok. so if someone asks write the equation of the line through(2 3) and parallel to y= 4x 1 how would i do thta

anonymous

Best ResponseYou've already chosen the best response.0Ok you know that the point (2,3) is going to be on the line of your answer. If two lines are parallel, that means they have the same slope.

Best ResponseYou've already chosen the best response.0So you would substitute your points in, giving you 3 = 4*2 + b

anonymous

Best ResponseYou've already chosen the best response.0So you have 3 = 8+b. What value of b do you need to make 3 = 8?

anonymous

Best ResponseYou've already chosen the best response.0Be careful. You need 11.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So since 11 is your b value, you construct your equation. y = 4x  11. You know that it's 4x because if two lines are parallel they have the same slope. We did those calculations to determine your b value.

Best ResponseYou've already chosen the best response.0so it goes back to the original y 4x1?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0No. Your answer would be y = 4x 11. This line is parallel to y = 4x 1 because they share the same slope.

Best ResponseYou've already chosen the best response.0the 3= 8 +b is used to find the parallel slope that i need

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0No, the 3 = 8 +b is used to determine your b value (Your yintercept)

anonymous

Best ResponseYou've already chosen the best response.0Two lines are parallel if they share the same slope. that's why you already know your slope for the problem because your answer has to have the same slope as your original line.

Best ResponseYou've already chosen the best response.0can we do one more with different points?

anonymous

Best ResponseYou've already chosen the best response.0Sure. Do you have an example?

anonymous

Best ResponseYou've already chosen the best response.0(2 5) parallel to y=2x+3

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Ok. Looking at y = 2x +3, What is the slope of our ansewr going to be?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0since they must be parallel

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Correct. So for our answer equation right now we have y = 2x + b. Now we must find out b value, and since we are given a point (2,5), we plug those points into our equation to find our b.

anonymous

Best ResponseYou've already chosen the best response.0You forgot to plug in your value for x.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Correct. Now what b value do we need to make that equation true?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Correct. Now what's our answer?

anonymous

Best ResponseYou've already chosen the best response.0this is where i get confused... how do i find this answer

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Oh ok. Well the question asks for a line, so we know our answer will be an equation of a line. We need the general form of our answer (meaning leaving x and y as x and y in the answer). We calculated our b value and we know our m value since it has to be parallel to our starting line. y = mx + b. Fill out that equation with the information we calculated (m value and b value).

anonymous

Best ResponseYou've already chosen the best response.0well slopes the same and b is 9 so its y=2x9?

anonymous

Best ResponseYou've already chosen the best response.0so on this everything fallls back to y=mx+b?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Now if you get an answer and your not sure about it, you can just plug in your given point into your answer and if you get the same thing on both sides the equation of your line works with your point.

anonymous

Best ResponseYou've already chosen the best response.0In this question yes it does. Since your looking for a line your answer will be in the form of y=mx+b

anonymous

Best ResponseYou've already chosen the best response.0and what if it asks for perpendicular? (1,1) perpindicular to y=2x+4

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Ok a Perpendicular line will have a slope that is the negative reciprocal of the slope of another line. So in this example look at 2 as (2/1). A reciprocal is when you flip the denominator and the numerator, so my reciprocal of 2/1 would be 1/2. Put a negative sign on that and that's the slope of my perpendicular line.

Best ResponseYou've already chosen the best response.0We will calculate our b value the same way as we did before.

anonymous

Best ResponseYou've already chosen the best response.0Yeah yeah I hear ya lol

anonymous

Best ResponseYou've already chosen the best response.0No you plug in your new slope to find the b value. Your new slope would be 1/2

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So we would have 1 = (1/2)*1 + b

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so on these you automatically flip the slope

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0On a perpendicular line yes. And you change the sign.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so then b would be 1/2?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0It would be 1/2. You have 1 = (1/2)*1 + b. 1/2 times 1 is just 1/2. So we're left with 1 = 1/2 + b. b has to be 1/2

anonymous

Best ResponseYou've already chosen the best response.0two negatives make a positive. so then we plug this back in to y=1/2x+1/2?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Two negatives make a positive in multiplication, not addition.

anonymous

Best ResponseYou've already chosen the best response.0But yes your equation is correct.

anonymous

Best ResponseYou've already chosen the best response.0And that's your answer.

Best ResponseYou've already chosen the best response.0awesome man i think i got it im having to teach myself this stuff cause i missed days lol

anonymous

Best ResponseYou've already chosen the best response.0Yeah. If you have a graphing calculator you can understand it better if your a visual learner. I'm more of a hands on / visual type learner myself so it helped me years ago when I was learning this stuff

anonymous

Best ResponseYou've already chosen the best response.0yea. the only way i learn is to beat it into my head lol. well thanks man can i add you on this site somehow in case i get in a rut?

Best ResponseYou've already chosen the best response.0well you can add me as fan. Idk if it will do anything but I try to get on here some.
