(\stackrel{x_1}{-1}~,~\stackrel{y_1}{-12})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{-8}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{-8}-\stackrel{y1}{(-12)}}}{\underset{\textit{\large run}} {\underset{x_2}{1}-\underset{x_1}{(-1)}}} \implies \cfrac{-8 +12}{1 +1} \implies \cfrac{ 4 }{ 2 } \implies 2
