# What is the slope of the line passing through the following points:  (-4, -1), (-2, -5) ?

formula of slope $, m = \frac{{y}_{1} - {y}_{2}}{{x}_{1} - {x}_{2}} ,$, where $\left({x}_{1} , {y}_{1}\right) \mathmr{and} \left({x}_{2} , {y}_{2}\right)$ are two points.
so $, m = \frac{- 1 - \left(- 5\right)}{- 4 - \left(- 2\right)} = \frac{4}{-} 2 = - 2 ,$
