Area of the two side triangles: 10 and 10 = 20
A = 1/2 bh
A = (10*2)/2 = 10
Area of rectangle:
A = l x w
A = 10 * 9
A = 90
90 + 20 = 110
X= -4
Your answer ^^^^
Answer:
y=-3/4x+3

Divide both sides by 4: y=-3/4y+3
translation and um thats all
top right is alternate interior and top left is corresponding
