Question

Help me please I don’t really understand how to do these types of problems

Answer 1

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

`(\stackrel{x_1}{-5}~,~\stackrel{y_1}{-4})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{-3}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-3}-\stackrel{y1}{(-4)}}}{\underset{run} {\underset{x_2}{1}-\underset{x_1}{(-5)}}} \implies \cfrac{-3 +4}{1 +5} \implies {\Large \begin{array}{llll} \cfrac{ 1 }{ 6 } \end{array}}`
