Answer:
Option D. − 8/5
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
we have the points
(−1, 7) and (4, −1)
substitute in the formula
[tex]m=\frac{-1-7}{4-(-1)}[/tex]
[tex]m=\frac{-1-7}{4+1}[/tex]
[tex]m=\frac{-8}{5}[/tex]
[tex]m=-\frac{8}{5}[/tex]
