Answer:
The value of m = -14 or the value of Slope = - 14
Explanation:
By the equation,
y = mx + 35 passing through the pts (8, -77) we can determine the value. Comparing the given equation with equation of straight line y=mx+c we can take the points 8,-77 as x and y.
Substituting x and y in the given equation,
-77 = m(8) + 35
Changing the sides,
8m + 35 = -77
8m = -77-35
8m = -112
m = -112/8
m = -14
