Starting at the point $\displaystyle{\left(-{5},-{1}\right)}\usepackage{cmbright}\Huge\$ , move two units up and then three units to the right to get to the point $\displaystyle{\left(-{2},{1}\right)}\usepackage{cmbright}\Huge\$ . The rise is 2 and the run is 3.

$\displaystyle{s}{l}{o}{p}{e}=\frac{{{r}{i}{s}{e}}}{{{r}{u}{n}}}=\frac{{2}}{{3}}\usepackage{cmbright}\Huge\$
