# What is the slope of the line passing through the following points:  (18,8) ; (-7,-5)?

Slope: $\frac{13}{25}$

#### Explanation:

For
$\textcolor{w h i t e}{\text{XXX}} \left(x 1 , y 1\right) = \left(18 , 8\right)$
and
$\textcolor{w h i t e}{\text{XXX}} \left({x}_{2} , {y}_{2}\right) = \left(- 7 , - 5\right)$

slope: $\frac{\Delta y}{\Delta x} = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}} = \frac{- 5 - 8}{- 7 - 18} = \frac{13}{25}$
