m = -1

Formula for finding the slope:

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

$P_{1} : (- 17, 13)$ $P_1: (-17, 13)$

$P_{2} : (- 18, 14)$ $P_2: (-18, 14)$

$m = \frac{13 - 14}{- 17 - - 18}$ $m = (13 - 14)/(-17 - -18)$

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

$m = - 1$ $m = -1$
