Answer:

(-2,15) (3,0)

Step-by-step explanation:

By substituting the x value in the coordinate (the first number in the bracket) and solving the equation, you must get the y value in the coordinate (second number in the bracket.

So that is to say:

A

y= -3x + 9

y = -3(-2) + 9

y = 6 + 9

y= 15

Also note that B is not one of them, because the y value you get when you substitute the x value in the equation is NOT NEGATIVE 6.
