Explanation:
The slope (m) of a line passing through two points (x1, y1) and (x2, y2) can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)
Using the points (7, -7) and (8, -13):
m = (-13 - (-7)) / (8 - 7)
m = (-13 + 7) / 1
m = -6 / 1
m = -6
So, the slope of the line passing through the points (7, -7) and (8, -13) is -6.
