OpenStudy (dtan5457):

The formula for direct variation is y=kx from 2x+6y=0, you want to isolate y and put into that form. Then solve for k

OpenStudy (anonymous):

K = 3?

OpenStudy (dtan5457):

So like 6y=-2x You can see that when y=6, x=-2 So 6=k(-2) Solve for k

OpenStudy (anonymous):

k = -1/3

OpenStudy (dtan5457):

What times -2 =6?
