Click on the graph to enlarge. The linear functions f(x) and g(x) are represented on the graph, where g(x) is a transformation of f(x). Which equation(s) can be used to transform f(x) to g(x)? Choose all that apply. A.
g(x) = f(x) - 4

B.
g(x) = f(x - 4)

C.
g(x) = f(x + 4)

D.
g(x) = f(x) + 4

B and D. I don't know how to explain it but those are the two answers on the nearpod.

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
