Answer

$m=-\dfrac{12}{5}$

Work Step by Step

Using $m=\dfrac{y_1-y_2}{x_1-x_2}$ or the Slope Formula, the slope of the line passing through the given points $( -3,4 )$ and $( 2,-8 )$ is \begin{array}{l}\require{cancel} m=\dfrac{4-(-8)}{-3-2} \\\\ m=\dfrac{4+8}{-5} \\\\ m=\dfrac{12}{-5} \\\\ m=-\dfrac{12}{5} .\end{array}
