$\frac{2}{15}$ $2/15$

Slope $m$ $m$ of a line passing through two points $A (x_{1}, y_{1})$ $A(x_1,y_1)$ and $B (x_{2}, y_{2})$ $B(x_2,y_2)$ is given by

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

Here let $A = (9, 9) and B = (- 6, 7)$ $A=(9,9) and B=(-6,7)$

$\Rightarrow m = \frac{7 - 9}{- 6 - 9} = \frac{- 2}{- 15} = \frac{2}{15}$ $implies m=(7-9)/(-6-9)=(-2)/-15=2/15$

$\Rightarrow$ $implies$ slope of the line passing through the given points is $\frac{2}{15}$ $2/15$ .
