$- \frac{7}{5}$ $-7/5$

Slope = $\frac{y_{1} - y_{2}}{x_{1} - x_{2}}$ $( y_1-y_2)/(x_1-x_2)$ pointing in the points gives

Slope = $\frac{5 - (- 9)}{- 3 - 7}$ ${5 - (-9)}/ (-3 -7)$ This gives

Slope = $\frac{14}{- 10}$ $14/-10$ = $\frac{7}{- 5}$ $7/-5$

$m = - \frac{7}{5}$ $m=-7/5$

If you are given two points, $(x_{1}, y_{1})$ $(x_1,y_1)$ and $(x_{2}, y_{2})$ $(x_2,y_2)$ , the slope, $m$ $m$ is defined to be:

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

In this case, the slope, $m$ $m$ is:

$m = \frac{- 9 - 5}{7 - (- 3)}$ $m=(-9-5)/(7-(-3))$

$m = - \frac{14}{10} = - \frac{7}{5}$ $m=-14/10=-7/5$
