Is 9-8x=y proportional
andrew-mc [135]

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
