Answer
Slope
Explanation:
Given the following points of the line, (-2, 1) and (4, -2)
Slope = rise / run
Rise = y2 - y1
Run = x2 - x1
Hence, slope = y2 - y1/ x2 - x1
From the given points
let x1 = -2, y1 = 1, x2 = 4 and y2 = -2
Slope = -2 - 1 / 4 - (-2)
Slope = -3 / 4 + 2
Slope = -3 / 6
Slope = -1/2
Hence, the slope of the line that contains the two points is -1/2
