Question

Does each equation represent a proportional relationship? Choose Yes or No. y = 7x – 3 , y = 150x

Answer 1

A proportional relationship has a general equation

y = kx

y = 7x - 3 is not proportional. No.

y = 150x is proportional. Yes.

Answer 2

Answer:

$y = 150x$ is a proportional relationship.

Step-by-step explanation:

We are given the following equations in the question:

$y = 7x - 3\\y = 150 x$

A proportional relationship is of the form:

$y = kx$

where k is a constant.

a)

$y = 7x-3$

It is not a proportional relationship as it does not take the form y = kx.

b)

$y = 150x$

It is a proportional relationship.

Comparing the equations, we get k = 150.
