Help!! Question 2/7 points) Find that quadrilateral ABCD with vertices A(0, 0), B(6,0), C(5,2), and D(1, 2) is an isosceles trapezoid by showing that its diagonals are congruent. Write SLOPES as reduced improper fractions or whole numbers (NO DECIMALS) Slope of AB = 0 Slope of BC = -2 Slope of CD = 0 Slope of DA = 2 Length of AC = (round to the nearest tenth) Length of BD = (round to the nearest tenth) Are the diagonals congruent? yes (yes/no)

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
