Final answer:
The slope of the line passing through the points (-5, -1) and (3, -1) is 0.
Step-by-step explanation:
To find the slope of a line passing through two points, we can use the formula:
m = (Y2 - Y1) / (X2 - X1)
Substituting the coordinates of the given points, we get:
m = (-1 - (-1)) / (3 - (-5))
Simplifying further, we have:
m = 0 / 8 = 0
Therefore, the slope of the line passing through the points (-5, -1) and (3, -1) is 0.
