Height of a trapezoid:
h = 5 · sin 80° = 5 · 0.985 = 4.924
x = 5 · cos 80° = 5 · 0.17365 = 0.868
7 - x = 7 - 0.868 = 6.132
By the Pythagorean theorem:
d² = 6.132² + 4.924²
d² = 37.6 + 24.25
d² = 61.85
d = √61.85
d = 7.86 ≈ 8

Answer:
slope = 3/5
Step-by-step explanation:
slope = rise/run = 3/5
or (longer way w/ the points)
slope = (y2-y1)/(x2-x1) = (5-2)/(4-(-1)) = 3/5
