Answer:
Choice B
Step-by-step 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.
