Answer:
slope of line is 5/7

Explanation:
The slope of the line can be calculated using the following rule:
slope = [tex] \frac{y2-y1}{x2-x1} [/tex]

The given points are:
(-9,-10) which represent (x1,y1)
(-2,-5) which represent (x2,y2)

Substitute with the points in the above equation to get the slope as follows:
slope = [tex] \frac{-5-(-10)}{-2-(-9)} [/tex] = 5/7

Hope this helps :)
