# How do you find the slope of a line passing through the points L(4,-2) and M(-12,-2)?

The slope of LM is $m = \frac{1}{2}$

#### Explanation:

The formula for slope is

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

For the coordinate points $\left(- 4 , 2\right) \mathmr{and} \left(- 12 , - 2\right)$
${x}_{1} = - 4$
${x}_{2} = - 12$
${y}_{1} = 2$
${y}_{2} = - 2$

$m = \frac{- 2 - 2}{- 12 - \left(- 4\right)}$

$m = - \frac{4}{-} 8$

The slope OF LM is $m = \frac{1}{2}$
