Answer:
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
From the question we have
[tex]m = \frac{8 - 5}{ - 8 - - 7} = \frac{3}{ - 8 +7 } = - \frac{3}{1} = - 3 \\ [/tex]
We have the final answer as
Hope this helps you
