Question

Find the slope of the line through each pair of points, (2,13), (6,10)

Answer 1

`(\stackrel{x_1}{2}~,~\stackrel{y_1}{13})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{10}) ~\hfill~ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{10}-\stackrel{y1}{13}}}{\underset{\textit{\large run}} {\underset{x_2}{6}-\underset{x_1}{2}}} \implies \cfrac{ -3 }{ 4 } \implies -\cfrac{3}{4}`
