Answer:
D
Explanation:
A and C aren't proportional relationships because a straight line denotes a constant of proportionality. They aren't straight so no such relationship exists. B is also incorrect because a proportional relationship means that
y = kx. When x = 0, y should also be 0, but it's not. So there is no proportional relationship between x and y for Option B.
(equation is y = x - 2)
Option D is a proportional relationship because the constant k of proportionality is 1/4. The function of Option D is y = x/4. Divide each y-value by its respective x-value and the answer will by 1/4 or 0.25 always.
