Answer:

Proportional.

Explanation:

We have been given that given an equation
y=-9x. We are asked to determine whether the given equation is proportional or not.

We know that two proportional quantities are in form
y=kx, where k is constant of proportionality.

We can see that our given equation is in form
y=kx, where
k=-9.

Therefore, the given equation is directly proportional.
