GIVING BRAINLIEST Referring to the figure, determine which of the following graphs best depicts this situation: A vacuum repair shop charges a fixed price plus a certain amount per half hour to repair a vacuum. Which graph best shows how much a customer is charged based on how long the job takes? a. Graph a c. Graph c b. Graph b d. Graph d

A is your answer.

Step-by-step explanation:

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

not sure but it may be b, as i said i'm not sure.
