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
(-17, 11) = (x₁, y₁)
(0, -7) = (x₂, y₂)
[lines usually go from left to right, so the point furthest to the left is the 1st point]
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{-7-11}{0-(-17)}[/tex] [two negative signs cancel each other out and become positive]
[tex]m=\frac{-7-11}{0+17}[/tex]
[tex]m=\frac{-18}{17}[/tex]
