Question

Is 9-8x=y proportional

Answer 1

Answer:

No, proportional relations are of the form,

$y = mx$

Step-by-step 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,

$y = mx$
