Answer:
-1.5
Step-by-step explanation:
The slope of a line is given by the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let's let (4,5) be x₁ and y₁ and let's let (8,-1) be x₂ and y₂. So:
[tex]m=\frac{-1-5}{8-4}[/tex]
Subtract:
[tex]m=\frac{-6}{4}[/tex]
Reduce:
[tex]m=-\frac{3}{2}=-1.5[/tex]
So, our slope is -3/2 or -1.5.
And we're done!
