Answer:

Step-by-step explanation:

Constants of proportionality appear in equations where the y intercept = 0

They are of the form y = ax

A: No. The y intercept is -3

C: No. The equation is not linear. It is of the form y = a/x which does not give a straight line. a = 21 and the y intercept is 0. It is just that the x is in the wrong place (in the denominator).

D is the same as A.

The answer is B and the constant is 150
