Find the slope of the line through the pair of points.

(8,-8) and (5,-8)

The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula:

slope = (y2 - y1) / (x2 - x1)

In this case, the points are (8, -8) and (5, -8). Plugging these values into the formula:

slope = (-8 - (-8)) / (5 - 8)

Simplifying:

slope = 0 / -3

This equals 0.

Therefore, the slope of the line passing through the pair of points (8, -8) and (5, -8) is 0.
