$m=-\dfrac{2}{7}$
Using $m=\dfrac{y_1-y_2}{x_1-x_2}$ or the Slope Formula, then the slope of the line containing the given points, $\left( -5,-1 \right) \text{ and } \left( 2,-3 \right)$, is \begin{array}{l} m=\dfrac{-1-(-3)}{-5-2} \\\\ m=\dfrac{-1+3}{-5-2} \\\\ m=\dfrac{2}{-7} \\\\ m=-\dfrac{2}{7} .\end{array}
