Which of the following lists is in order from smallest to largest A. -3, |3|, 0, (-3)^2
B. (-3)^2, -3, 0, |3|
C. -3, 0, |3|, (-3)^2
D. 0, -3, |3|, (-3)^2

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

noncoplanar points are points that do not lie on the same line.
