What’s the slope of the line containing the given points?

The answer to your question is below

Step-by-step explanation:

Formula

5.- A (-2, 2) B(0, 4)

                                 m =  

                                   m = 1

6.- R(5, -1)  S (2, 3)

7.- M (4, 8) N (6, -1)

8.- F (5, -5) G (-1, 6)

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
