Question

Determine whether the representation is proportional.y= -9x

Answer 1

Yes it is proportional

Answer 2

Yes it is

Explanation:

y=-9x means that for every x value, the y value decreases by 9, so it is proportional because the value of y decreases the same amount each time. For example, if x=1, y=-9. If x=5, y=-45, and so on.
