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.

AfilCa [17]

Product is multiplication:

x * (x+2) = 201

x^2 +2x = 120

x^2 + 2x -120 = 0

(x+12) (x-10) = 0

x = -12 and x = 10

-12 x -1 = 12

the 2 numbers are 10 and 12
