Answer:
-11/10
Step-by-step explanation:
Slope = rise/run
m = (12-1) / (-19-(-9))
m = -11/10
To find the slope(m), use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] And plug in the two points
(-19, 12) = (x₁, y₁)
(-9, 1) = (x₂, y₂)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{1-12}{-9-(-19)}[/tex] (two negative signs cancel each other out and become positive)
[tex]m=\frac{1-12}{-9+19}[/tex]
[tex]m=\frac{-11}{10}[/tex]
