Which equation is an example of a direct variation?

a.) y = 2/3 xz
b.) 2 xy = 12
c.) y = 8/x
d.) 2/3 x = y

(2/3)*x = y is an example of direct variation because it can be rewritten as 2/3 = y/x where if x increases y also increases.

D

Step-by-step explanation:

D is the sole equation that demonstrates direct variation, so long as you meant y = (2/3)x.  This has the form y = kx, where k is the constant of proportionality.
