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.
