The answer is D. I know this because all you have to do is use a calculator, and fill in the x and y values in the equation from your answers, and see which one adds upp..(:

tanvirms Group TitleBest ResponseYou've already chosen the best response.1
in an ordered pair, the first number is the value of x and the second one is y, so, just put the value of x and y and see which gets u 5 ..... *sshhh* its the last one :P

well idk this one cuz i don't get slopes :/
 one year ago

Heyy_Girl_Heyy Group TitleBest ResponseYou've already chosen the best response.0
I can explain slopes if you want me to
 one year ago

Heyy_Girl_Heyy Group TitleBest ResponseYou've already chosen the best response.0
I know the answer, but I want to make sure you UNDERSTAND the material.
 one year ago

tanvirms Group TitleBest ResponseYou've already chosen the best response.1
it ascends from left to right, which means it has a positive slope...with this info, u can eliminate 2 answer choices :) (elimination is a wonderful strategy for SAT)

rise/run from one point to the next: how many units up (if its down its negative) over how many units right (left means negative)
 one year ago

Heyy_Girl_Heyy Group TitleBest ResponseYou've already chosen the best response.0
Okay, so when you are doing slope, you use rise over run. Rise is the up or down along the grid, and run is side to side across the grid. So you will measure you r rise )Up or down motion) as opposed to your run(Side to side motion) count how many there are and thats your answer
 one year ago

Heyy_Girl_Heyy Group TitleBest ResponseYou've already chosen the best response.0
O meant how ever many units up or down and across from each point is your answer.

equation for slope: \[m = \frac{ y_{2}–y_{1} }{x_{2}–x_{1}}\]
 one year ago

Heyy_Girl_Heyy Group TitleBest ResponseYou've already chosen the best response.0
No, it will be in the form of a frac tion
 one year ago

goldyyy Group TitleBest ResponseYou've already chosen the best response.0
so is it always in fraction form?
 one year ago

Heyy_Girl_Heyy Group TitleBest ResponseYou've already chosen the best response.0
Most times.
 one year ago

Heyy_Girl_Heyy Group TitleBest ResponseYou've already chosen the best response.0
Yeah.!
 one year ago

tanvirms Group TitleBest ResponseYou've already chosen the best response.1
it doesnt need to be fraction...it can be any number.
 one year ago

Heyy_Girl_Heyy Group TitleBest ResponseYou've already chosen the best response.0
Well, in this case it would be a fraction, correct?
 one year ago

tanvirms Group TitleBest ResponseYou've already chosen the best response.1
yup...basically, when the run is greater than the rise, it has a chance to be a fraction.

and for number 3, i tried all the answers but they all equaled 24 or 24 and 26 or 26

hmm, the same thing happened with me. I am not sure.

intercept is the point where the straight line cuts the axis...so, x intercept means that value of x for which y=0, and y intercept means that value of y for which x=0....try solving

would it be B because the answer is 12 and B's answer is 24 which is double?
 one year ago

tanvirms Group TitleBest ResponseYou've already chosen the best response.1
2x3y=12, or, 3y=2x12 pr. 3y=2x+12 or, y=(2x+12)/3 now, find that value of x for which y would be 0. in this case, it is 6.... (12+12)/3=0 similaryl, 2x=3y12 or, x=(3y12)/2 for y=4, x=0....so the correct answer is B,

goldyyy Group TitleBest ResponseYou've already chosen the best response.0
yes so i was right! what about these?
 one year ago

goldyyy Group TitleBest ResponseYou've already chosen the best response.0
last one got cut off so here
 one year ago

tanvirms Group TitleBest ResponseYou've already chosen the best response.1
for the first one, do that same as @Heyy_Girl_Heyy taught u a while ago... for the second one, all u have to do is get the equation in y=mx+c form so, 4x+9y=36 or, 9y=4x+36 or, y=4/9.x + 36/9 or, y=4/9.x+4

Q.9what is the relationship between these two lines: 3x+6y=8 y=2x8 as i said, try to transform the equation into y=mx+b form, the second one is already done...lets go with the first one. 3x+6y=8 or, 6y=3x+8 or, y= 3/6.x + 8/6 or, y= 1/2.x + 4/3 what u wanna look at now is the part with x (the 'm' part in y=mx+b) and in this case it is 1/2 (u have to take it with the sign)....it is the 'slope' in case of y=2x8 slope, m is 2, right? whats the relationship between 2 and 1/2?? 1/2 is the reciprocal of 2 with the opposite sign (u know what a reciprocal fraction is, right?) when one straight line has a reciprocal slope with the opposite sign in respect to another straight line, they are perpendicular to each other. i hope this explains.

Q. which has a slope of 5 and y intercept of 3? all of these equations are in intercept form. ( y=mx+b as i said) m is the slope b is the y intercept so what u are looking for is an equation that has m=5, b=3 look for it!!

Q. which one is graph of inequality y<2x+3 the shaded part is the part that denotes the inequality, i guess u already know that. if there's a straight line between the shaded part and the white part, there should be a = sign in the equation....you dont see any '=' in the equation, do you? in that case, you can just eliminate B. now, the best way is to take a (x,y) pair. and the easiest to work with is the (0.0) pair. substitute the values of x and y here. 0<2.0+3 or, 0<3 which is totally true (0,0) lies in the shaded part of C, so C is the answer. sometimes, you might also have to check some other pairs (1,1) or something else too, just to be sure. if you'r wondering whether A is correct or not, take a point that lies in the shaded part, lets say it is (2,4) (its in the shaded part, check out) 4<2.(2)+3 or, 4<4+3 or, 4<1 apparently, 4 can never be less than 1. so there you go...its not A, not B...its C.

i believe we already worked on 5 and 6 a while ago...check. Q.7a line that passes through (2,1) and has a slope of 5. if my earlier explanations were clear enough, i believe you already know that only option A and B has a slope of 3 now, check them with the pair (2,1). you wanna put x=2 and y=1 and see if its true. for A, (1+1)=3(2+2) or, 2=0 TOTALLY WRONG! for B, (11)=3(2+2) or 0=0 there you go!! Q.8: what is the slope of the line parallel to 2x3y=6 find the slope first. 3y=2x+6 or, 3y=2x6 or, y=2/3.x2 so, the slope is 2/3, right?? remember what i told you a while ago? perpendicular lines have a reciprocal and opposite signed slope..... in case of parallel lines, they have the same slope. so, the answer is 2/3..

finally, i'm sorry for the late replies. i'm from Bangladesh and our time zones are totally different. it was like 2 AM in the morning and i went to bed (not to mention, i got struck by AlterBridge too. listened to them over and over again till 4 xD ).
