Use the graph to answer the question. what are the coordinates of point p? 5 4 3 א א א א 1 e 6-5-4 3 1 2 3 4 5 6 х -2-1 -1 -21 OP -4 -5 What are the coordinates of point P? A. (-3,-2) B. (-2,-3) C. (-2,3) D. (3,-2)

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
