Question

Is y=-9x proportional

Answer 1

Answer:

Proportional.

Step-by-step 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.

Answer 2

Yes, y=-9x is proportional
