Which of the following rational functions is graphed below?

if you mean

then it's c. 8, -7/3

but if you mean

then it is

the answer to the question is a  

it has the same slope and the same y-intercept.

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

3 is greater then both of those numbers
