1) Let's find the slope through the slope-intercept form equation
Let's choose two points (12,-10) (17,2)
Plugging into the slope-intercept form of the linear function formula:
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1}\text{ } \\ m=\frac{2-(-10)}{17-12} \\ m=\frac{12}{5} \end{gathered}[/tex]So, the slope of this line is 12/5
