Question

Which equation represents a non proportional relationship?


A y = 3x + 5
B y = −3x
C y = 1/3x
D y = 3x + 0

Answer 1

Answer:

A

Step-by-step explanation:

The answer is A because in order for a relationship to be proportional, it must go through the origin, or (0,0). This means that all proportional relationships have a y-intercept of 0 because there is no initial value. A is the only answer choice that has a y-intercept that is not 0.

Answer 2

It’s A. It’s doesn’t go through the origin
