# How do you find the slope of (-4,-8); (-2,0) without a graph?

Jan 30, 2016

m = 4

#### Explanation:

To find slope use the$\textcolor{b l u e}{\text{ gradient formula}}$

$m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

where ( x_1 , y_1) ,(x_2 , y_2 )color(black)( " are 2 points ")

for this question let

$\left({x}_{1} , {y}_{1}\right) = \left(- 4 , - 8\right) \textcolor{b l a c k}{\text{ and }} \left({x}_{2} , {Y}_{2}\right) = \left(- 2 , 0\right)$

substitute values into formula :

$m = \frac{0 - \left(- 8\right)}{- 2 - \left(- 4\right)} = \frac{8}{2} = 4$
