$- \frac{3}{7}$ $-3/7$

Explanation:

The slope $m$ $m$ of the line passing through the points $(x_{1}, y_{1}) \equiv (- 5, 1)$ $(x_1, y_1)\equiv(-5, 1)$ & $(x_{2}, y_{2}) \equiv (9, - 5)$ $(x_2, y_2)\equiv(9, -5)$ is given by following formula

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $m=\frac{y_2-y_1}{x_2-x_1}$

$= \frac{- 5 - 1}{9 - (- 5)}$ $=\frac{-5-1}{9-(-5)}$

$= - \frac{6}{14}$ $=-6/14$

$= - \frac{3}{7}$ $=-3/7$
