# How do you find the slope of the line passing through the points (1,1) and (-4,-4)?

$\text{slope } = 1$

#### Explanation:

$\text{to calculate the slope m use the "color(blue)"gradient formula}$

•color(white)(x)m=(y_2-y_1)/(x_2-x_1)

$\text{let "(x_1,y_1)=(1,1)" and } \left({x}_{2} , {y}_{2}\right) = \left(- 4 , - 4\right)$

$\Rightarrow m = \frac{- 4 - 1}{- 4 - 1} = \frac{- 5}{- 5} = 1$
