Question

Does each equation represent a proportional relationship? Choose Yes or No.

y = 7x – 3 yes or no

y = 150x yes or no

Answer 1

y=150x is proportional, but y=7x-3 is not.

Explanation:

A proportional relationship is of the form where k is a constant. It is not a proportional relationship as it does not take the form y = kx. It is a proportional relationship, so we get k = 150.
