$m = - 4$ $m=-4$

You can find the slope by the formula:

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

where $(x_{1}, y_{1}) and (x_{2}, y_{2})$ $(x_1,y_1) and (x_2,y_2)$ are two different points of the line.

In this case,

$m = \frac{5 + 7}{2 - 5}$ $m=(5+7)/(2-5)$

$m = \frac{12}{- 3}$ $m=12/-3$

$m = - 4$ $m=-4$
