OpenStudy (solomonzelman):

Direct equation looks like y=Kx Indirect y=Kx+a (unless a is zero. basically.

OpenStudy (anonymous):

so B?

OpenStudy (anonymous):

I mean C!

OpenStudy (solomonzelman):

it is asking for what is NOT a direct variation.

OpenStudy (anonymous):

Is A and C right?

OpenStudy (solomonzelman):

What is the equation of the line, can you find it?

OpenStudy (anonymous):

to find that find slope . fist find 2 point and find the changes in y s and x s . for example : (3,2) and (-3,-2) y2=-2 x2=-3 x1=3 y1=2 we find m(slope) from this way : Y2-Y1/X2-X1 -2-2/-3-3 = -4/-6 = 4/6 = 2/3 and this is the answer ;)

OpenStudy (anonymous):

so thats the only answer??? C?

OpenStudy (anonymous):

y
