find the slope of each line

Answer:
[tex]m=\frac{-1}{3}[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in the 2 coordinates into the slope formula to find slope m:
(-1, -1)
(2, -2)
[tex]m=\frac{-2-(-1)}{2-(-1)}[/tex]
[tex]m=\frac{-2+1}{2+1}[/tex]
[tex]m=\frac{-1}{3}[/tex]
