The graph shows the height, y, in centimeters, of a plant after a certain number of weeks, x. Donna drew the line of best fit on the graph.
What would most likely be the approximate height of the plant after 8 weeks?

11.0 centimeters
9.25 centimeters
8.8 centimeters
7.4 centimeters

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

10.4 inches
