On a coordinate plane, plot points A, B, and C such that B is the only point AB¯¯¯¯¯ and BC¯¯¯¯¯ have in common and neither of those line segments is horizontal or vertical. Give and then follow the steps needed to construct the unique point D such that AD¯¯¯¯¯∥BC¯¯¯¯¯ and AB¯¯¯¯¯∥CD¯¯¯¯¯ . Find the slopes of those line segments, and explain how they confirm those pairs of line segments are parallel.

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

i dont know men

step-by-step explanation:

yes.. it's proven to be 36.

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
