# What is the slope of the line passing through (-7,0); (-2,-6)?

#### Explanation:

The formula for find the slope of a line is:

$m = \frac{\textcolor{red}{{y}_{2}} - \textcolor{b l u e}{{y}_{1}}}{\textcolor{red}{{x}_{2}} - \textcolor{b l u e}{{x}_{1}}}$

Where $\left(\textcolor{b l u e}{{x}_{1}} , \textcolor{b l u e}{{y}_{1}}\right)$ and $\left(\textcolor{red}{{x}_{2}} , \textcolor{red}{{y}_{2}}\right)$ are two points on the line.

Substituting the values from the points in the problem gives:

$m = \frac{\textcolor{red}{- 6} - \textcolor{b l u e}{0}}{\textcolor{red}{- 2} - \textcolor{b l u e}{- 7}} = \frac{\textcolor{red}{- 6} - \textcolor{b l u e}{0}}{\textcolor{red}{- 2} + \textcolor{b l u e}{7}} = - \frac{6}{5}$
