Knowing the points a(1, 6), b(−5, −2), c(−1, −5), and d(5, 3), and that segment ab is parallel to segment cd, what is the length of segment ab and segment cd comma and do points a, b, c, and d form a parallelogram? hint: to prove these points form a parallelogram, segment ab and segment cd must be equal in length

step-by-step explanation:

1/4 = .25 / 25%

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
