Question

Which is not a proportianal relationship A y=x, B x-y=2, C=y=2x and D x +2y=0

Answer 1

Choice B

Explanation:

Choice B is not a proportional relationship because it is not in the form of Y = KX.

First, you must convert the equation, X - Y = 2 to Y = MX + B by subtracting X to the right side to get -Y = -X +2. Then divide each side by -1 to get a positive Y value. Then you are left with Y = X - 2, which is not in the form of Y=KX.
