Answer: -1
Explanation:
To find the slope of the line that contains the points (-8, -1) and (-5, -4), we can use the following formula:
slope = (change in y) / (change in x)
So, if we plug in the coordinates of the two points, we get:
slope = (-4 - (-1)) / (-5 - (-8))
slope = (-4 + 1) / (-5 + 8)
slope = -3 / 3
slope = -1
Therefore, the slope of the line that contains the points (-8, -1) and (-5, -4) is -1.
