Question

Find the slope of the line through the following pair of points. Show all of your work.

(−5, −20), (9, 9)

Answer 1

`(\stackrel{x_1}{-5}~,~\stackrel{y_1}{-20})\qquad (\stackrel{x_2}{9}~,~\stackrel{y_2}{9}) ~\\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{9}-\stackrel{y1}{(-20)}}}{\underset{run} {\underset{x_2}{9}-\underset{x_1}{(-5)}}} \implies \cfrac{9 +20}{9 +5} \implies {\large \begin{array}{llll} \cfrac{ 29 }{ 14 } \end{array}}`
