To find the slope(m), use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] And plug in two points on the line. I will use
(-2, 1) = (x₁, y₁)
(4, -6) = (x₂, y₂)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{4-(-2)}{-6-1}[/tex] (two negative signs cancel each other out and become positive)
[tex]m=\frac{4+2}{-6-1}[/tex]
[tex]m=\frac{6}{-7}[/tex]
