Question

PLS PLS HELP URGENT x Which graph shows a proportional relationship between x and y?

Answer 1

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.

Answer 2

D

Explanation:

Because consecutively when the line heads up, it goes (8,2) then (12,3) then (16,4)

This is a relationship proportionally because for every 4 the x goes up, the y will go up 1
