Answer:
9
Step-by-step explanation:
To find the slope of a line, calculate the distance between points with a ratio of vertical to horizontal distance. This is done using the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here the points are (-7,-2) and (-6,7). Substitute and simplify.
[tex]m=\frac{7--2}{-6--7}=\frac{7+2}{-6+7}=\frac{9}{1}=9[/tex]
