Answer:
No, proportional relations are of the form,
[tex]y = mx[/tex]
Step-by-step explanation:
The given equation is
[tex]9 - 8x = y[/tex]
This is an equation in the form:
[tex]y = mx + c[/tex]
since we can rewrite to get:
[tex]y = - 8x + 9[/tex]
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,
[tex]y = mx[/tex]
