Which representation represents a proportional relationship? A x 2 4 6 8 y 6 8 10 12 B y is equal to 2 x plus 2 C Open image in full-screen view D x 4 7 12 15 y 8 14 24 30

A proportional relationship has a constant ratio of y to x. In representation D, each y-value is twice its matching x-value: 8/4 = 14/7 = 24/12 = 30/15 = 2. So representation D is proportional, and it corresponds to choice C.
