# How do you find the slope given (1,1) (-2,-2)?

Jul 12, 2016

The slope equals $m = 1$

#### Explanation:

Slope which is the change in $x$ versus the change in $y$.

Slope is identified by the letter $m$

$m = \frac{\Delta y}{\Delta x}$

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

$\left(1 , 1\right)$ and $\left(- 2 , - 2\right)$

${x}_{1} = 1$
${y}_{1} = 1$
${x}_{2} = - 2$
${y}_{2} = - 2$

$m = \frac{\left(- 2\right) - 1}{\left(- 2\right) - 1}$

$m = \frac{- 3}{- 3}$

The slope equals $m = 1$
