Answer:
[tex]m=\frac{-8}{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:
[tex]m=\frac{-5-3}{1-(-2)}[/tex]
[tex]m=\frac{-8}{1+2}[/tex]
[tex]m=\frac{-8}{3}[/tex]
Parallel lines have the same slope.
