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 ...?

I think you have a typo in you choices...

y = -4/3 x is the answer...

which is the same as y = - 1 1/3 x

you don't have that choice, "A" and "C" are the same..

I think that one of them is "y = - 1 1/3 x "

y = kx

-12 = k 9

k = -12/9 = -4/3
