Question

Find the slope of the line: (8, -3), (10, 7)

Answer 1

`(\stackrel{x_1}{8}~,~\stackrel{y_1}{-3})\qquad (\stackrel{x_2}{10}~,~\stackrel{y_2}{7}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{7}-\stackrel{y1}{(-3)}}}{\underset{\textit{\large run}} {\underset{x_2}{10}-\underset{x_1}{8}}} \implies \cfrac{7 +3}{2} \implies \cfrac{ 10 }{ 2 } \implies 5`
