9) Area of Figure = Area of rectangle + area of triangle
A = 17 * 22 + (1/2 * 12 * 19)
A = 374 + 114
A = 488 cm²
10) Area of Figure = Area of rectangle + area of triangle
A = 8 * 4 + (1/2 * 3*4)
A = 32 + 6
A = 38 cm²
Hope this helps!
We need to check the ordered pairs for x = -2, x=5, x= 2/3 and x = 0.75.
1. For the first function: y = 9-4x
x=-2

The ordered pair is (-2,17).
x = 5

The ordered pair is (5,-11).
x = 2/3

The ordered pair is (2/3, 19/3)
x = 0.75
