Answer:
Equation of a line has form of y = ax + b
This line passes (-8, 8) and (1, 10), then:
-8 = -8 x a + b
10 = a + b
Subtract 2nd equation to 1st equation, then:
18 = 9 x a
=> a = 2
=> b = 10 - 2 = 8
=> y = 2x + 8
Hope this helps!

Answer:
53
Step-by-step explanation:
1) Take the area of the rectangle from origin to Point B. We see that it is 8 * 11 = 88 units of area
2) We subtract all the triangles in the rectangle that are not covered by the shape.
So
- Triangle FAPoint(0,-8) area = 1/2 * 2 * 5 = 5
- Triangle FEPoint(0,-3) area = 1/2 * 3 * 4 = 6
- Rectangle P(0,0) P(0,-3) P(6,-3) P(6,0) area = 6 * 3 = 18
- Triangle DP(6,0)P(11,0) area = 1/2 * 5 * 3 = 7.5
Take the area of the big imaginary rectangle and subtract the area of all the smaller triangles and the smaller rectangle
88 - 5 - 6 - 7.5 - 18 = 51.5
Done!
