We use the point-slope formula

$\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $( color(green)(y_2)- color(red)(y_1) )/(color(green)(x_2)-color(red)(x_1))$

$(- 7, 2)$ $(color(green)(-7), color(green)(2))$ and $(9, 6)$ $( color(red)(9), color(red)(6) )$

$\frac{6 - 2}{9 - - 7}$ $(6-2)/(9- -7)$

$\frac{4}{16}$ $4/16$

$\frac{1}{4}$ $1/4$

That's the slope!
