The formula of a slope:

We have m = -2 and the points (0, d) and (-8, 9). Substitute:

Answer: -2/3
3-(-1) over
-2-4
This equals 4/-6 which reduces to -2/3
Answer:
81.75 ft²
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A =
h (a + b)
where a, b are the parallel bases and h is the perpendicular height
Calculate h using the right triangle and the sine ratio
sin30° =
= 
Multiply both sides by 10
10 × sin30° = h, thus
h = 5
a = 12 and b = 8.7 + 12 = 20.7, hence
A =
× 5 × (12 + 20.7)
= 0.5 × 5 ×32.7
= 81.75 ft²
