A parallelogram is a four-sided figure whose opposite sides are parallel and equal in length. Alex is drawing
parallelogram ABCD on a coordinate plane. The
parallelogram has the coordinates A(4,2), B(0, -2), and
D(8,-1).

Which of the following coordinates should Alex use for point C?

A. 6-3)
B. (4, 5)
C. (10.-3)
D. (4,3)

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

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
