Answer:
The slope of the line through (-1, 8) and (3, -4) = m = -3
Explanation:
Given the points
Determining the slope between (-1, 8) and (3, -4)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [-4 - 8] / [3 - (-1)]
= [-12] / [3+1]
= -12/4
= -3
Thus, the slope of the line through (-1, 8) and (3, -4) = m = -3
