How do you find the slope given (-7, 2) and (9, 6)?

Apr 7, 2018

We use the point-slope formula

$\frac{\textcolor{g r e e n}{{y}_{2}} - \textcolor{red}{{y}_{1}}}{\textcolor{g r e e n}{{x}_{2}} - \textcolor{red}{{x}_{1}}}$

$\left(\textcolor{g r e e n}{- 7} , \textcolor{g r e e n}{2}\right)$ and $\left(\textcolor{red}{9} , \textcolor{red}{6}\right)$

$\frac{6 - 2}{9 - - 7}$

$\frac{4}{16}$

$\frac{1}{4}$

That's the slope!
