Final answer:
The slope of the line passing through the points (-20, -5) and (-13, -5) is 0.
Step-by-step explanation:
The slope of a line can be found using the formula:
slope = (y2 - y1) / (x2 - x1)
Substituting the given points (-20, -5) and (-13, -5) into the formula:
slope = (-5 - (-5)) / (-13 - (-20))
slope = 0 / 7
Therefore, the slope of the line passing through the points (-20, -5) and (-13, -5) is 0.
