Please Help Me, Ive tried asking people but nobody knows :( (Image In Question) Which equation best models the data shown in the scatter plot?

A. y = x − 3

B. y = 3x − 3

C. y = x − 5

D. y = 3x − 5

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
