Question

Is 9-8x=y proportional

Answer 1

No, proportional relations are of the form,

`y = mx`

Explanation:

The given equation is

`9 - 8x = y`

This is an equation in the form:

`y = mx + c`

since we can rewrite to get:

`y = - 8x + 9`

This equation has a non-zero y-intercept and does not pass through the origin.

A proportional relation, will have a zero y-intercept and pass through the origin.

Therefore a proportional relation is of the form,

`y = mx`
