Question

How do I find the slope in this problem?

Answer 1

to get the slope of any straight line, we simply need two points off of it, let's use the points in the picture below

`(\stackrel{x_1}{-5}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{1}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{1}-\stackrel{y1}{3}}}{\underset{run} {\underset{x_2}{0}-\underset{x_1}{(-5)}}} \implies \cfrac{-2}{0 +5} \implies \cfrac{ -2 }{ 5 } \implies {\Large \begin{array}{llll} - \cfrac{2 }{ 5 } \end{array}}`
