Triangle X with vertices (−2, 4), (2, 4), and (−2, 2)

Triangle Z with vertices (−2, 4), (2, 4), and (−2, 3)

Triangle Y with vertices (−1, 4), (1, 4), and (−1, 2)

Triangle W with vertices (−2, 0), (2, 0), and (−2, −1)

Step-by-step explanation:

Triangle X with vertices (−2, 4), (2, 4), and (−2, 2)

6.5

step-by-step explanation:

you said it was in the question

~courtney

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
