The point slope form of the line with slope m going through the point $\displaystyle{\left({x}_{{1}},{y}_{{1}}\right)}\usepackage{cmbright}\Huge\$ is $\displaystyle{y}-{y}_{{1}}={m}{\left({x}-{x}_{{1}}\right)}\usepackage{cmbright}\Huge\$ so the point slope form of the given line is $\displaystyle{y}-{1}={3}{\left({x}-{2}\right)}.\usepackage{cmbright}\Huge\$
