$m = - \frac{1}{2}$ $m=-1/2$

Explanation:

Given -

$x_{1} = - 2$ $x_1=-2$
$y_{1} = - 1$ $y_1=-1$
$x_{2} = 4$ $x_2=4$
$y_{2} = - 4$ $y_2=-4$

Slope $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{- 4 - (- 1)}{4 - (- 2)} = \frac{- 4 + 1}{4 + 2} = \frac{- 3}{6} = - \frac{1}{2}$ $m=(y_2-y_1)/(x_2-x_1)=(-4-(-1))/(4-(-2))=(-4+1)/(4+2)=(-3)/6=-1/2$

$m = - \frac{1}{2}$ $m=-1/2$
