First, make sure the equation is in y-form.
Second, plot "y=" line (make it solid line for y greater/lesser than equal; and dashed line for y is greater/less than.
Lastly, shade the above line for a "greater than" / greater than equal;
shade the lower line for a "less than"/ lesser than equal.
First, plot two points that satisfy the inequalitiy such that it is an equality. then connect them. then check which half-plane works.
