Answer 2

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.
