slope of -9,-8 and 12,-1

To find the slope of the line passing through the points (-9, -8) and (12, -1), we can use the slope formula:

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

Let's label the coordinates as follows:
x1 = -9
y1 = -8
x2 = 12
y2 = -1

Substituting these values into the formula, we get:

slope = (-1 - (-8)) / (12 - (-9))
= (-1 + 8) / (12 + 9)
= 7 / 21
= 1/3

Therefore, the slope of the line passing through the points (-9, -8) and (12, -1) is 1/3.
