Incorrect. $\displaystyle{x}_{{1}}=-{8}\usepackage{cmbright}\Huge\$ , $\displaystyle{y}_{{1}}={5}\usepackage{cmbright}\Huge\$ , $\displaystyle{x}_{{2}}=-{2}\usepackage{cmbright}\Huge\$ , and $\displaystyle{y}_{{2}}=-{7}\usepackage{cmbright}\Huge\$

Substitute the values into the slope formula $\displaystyle{m}=\frac{{{y}_{{2}}-{y}_{{1}}}}{{{x}_{{2}}-{x}_{{1}}}}\usepackage{cmbright}\Huge\$ and simplify.

The correct answer is $\displaystyle-{2}\usepackage{cmbright}\Huge\$ .
