What is the direct linear variation equation for the relationship?
y varies directly with x and y = 4 when x = 12.
A. Y=3X
B. Y=X+8
C. Y=1/3X
D. Y=X-8

Answer 1

Direct variation means y = kx, where k is a constant.
Plug in 4 for y and 12 for x to solve for k.

Answer 2

Choice C Should be made clearer. it should be y = x/3 the way it is shown now make y look like an inverse relationship. A, B, and D are incorrect.

Answer 3
