Answer:
m = -3/4
Explanation:
Calculation of the Slope of a line
The information provided about the line is that the line passes through the points (-8, 9) to (-4,6)
Therefore, the first step consists in computing the slope. The formula for the slope is:

Now, by plugging the corresponding numbers is , we get that the slope is:

So then, we find that the slope is
and that the line passes through the point
.
