Answer:

Explanation:

B

If the y intercept is anything but 0, then the linear function is not proportional. So A is not proportional (2 is the y intercept)

C is a quadratic and it will not give proportional results. y/x is not a constant.

D has no x value and is not going to give a proportional result. y/x is undefined.
