Question

If two points on a line are A(10, -3) and B(8, -8) the rise is and run is?

Answer 1

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