What is the slope of the line passing through  (7,-2) ;(-6,7) ?

$\text{slope } = - \frac{9}{13}$

Explanation:

$\text{to calculate the slope m use the "color(blue)"gradient formula}$

•color(white)(x)m=(y_2-y_1)/(x_2-x_1)

$\text{let "(x_1,y_1)=(7,-2)" and } \left({x}_{2} , {y}_{2}\right) = \left(- 6 , 7\right)$

$\Rightarrow m = \frac{7 - \left(- 2\right)}{- 6 - 7} = \frac{9}{- 13} = - \frac{9}{13}$
