How can we find the slope of the line passes through these points A(-3,6) and B(2,5)?

Thanks

the slope $m$ of the line passes through two points $A(x_{1}, y_{1})$ and $B(x_{2}, y_{2})$ is given by the following formula:

$m=\frac{ y_{2}- y_{1}}{ x_{2}- x_{1}}$

Applying the above formula we can find the slope of the line
$m=\frac{5-6}{2-(-3)}= -\frac{1}{5}$
