Question

Find the slope of the following graph and choose the correct result.​

Answer 1

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

`(\stackrel{x_1}{10}~,~\stackrel{y_1}{50})\qquad (\stackrel{x_2}{70}~,~\stackrel{y_2}{70}) ~\hfill~ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{70}-\stackrel{y1}{50}}}{\underset{\textit{\large run}} {\underset{x_2}{70}-\underset{x_1}{10}}} \implies \cfrac{ 20 }{ 60 } \implies \cfrac{1}{3}`
