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
(-5, 3) = (x₁, y₁)
(7, 9) = (x₂, y₂)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{9-3}{7-(-5)}[/tex] [two negative signs cancel each other out and become positive]
[tex]m=\frac{9-3}{7+5}[/tex]
[tex]m=\frac{6}{12}[/tex] Simplify
[tex]m=\frac{1}{2}[/tex]
