When $\displaystyle{x}=-{3}\usepackage{cmbright}\Huge\$ and $\displaystyle{y}={2}\usepackage{cmbright}\Huge\$ then $\displaystyle{y}-{3}=-{1}\usepackage{cmbright}\Huge\$ and $\displaystyle{4}{\left({x}+{2}\right)}=-{4},\usepackage{cmbright}\Huge\$ so $\displaystyle{y}-{3}\ne{4}{\left({x}+{2}\right)}\usepackage{cmbright}\Huge\$ when $\displaystyle{\left({x},{y}\right)}={\left(-{3},{2}\right)}\usepackage{cmbright}\Huge\$ . Therefore (-3, 2) does not lie on the line.
