You can put this solution on YOUR website! I tried to figure this problem out and I got y = -12/9x. I am not sure if it is right and I need help Thank You.
Write an equation of the direct variation that includes the point (9,-12)
-------------------------
y = kx expresses direct variation between the variables x and y.
---------
Knowing that y = -12 when x = 9 allows you to solve for "k":
-12 = k(9)
k = -4/3
------------
So the equation you want is y = (-4/3)x
