Write an equation of the direct variation that includes the point (9, –12).


(A.) y = 1 1/3x (B.) y = - 1/12x (C.) y = 1 1/3x (D.) -3/4x ...?

Verified Answer :

The solution to the problem is as follows:

In general a direct variation is of the form y = kx. With the point (9, -12), then x = 9 and y = -12, we can now solve for k, the proportionality constant.
-12 = k(9)
k = -4/3
