When an inequality contains both x and y the graph will require the full grid instead of a simple number line. To graph the inequality start by graphing the line as an equation.
Use a dashed line if the inequality is > or < to show that the points on the line do not belong to the solution. Use a solid line if it is ≥ or ≤. Then test any point that
does not fall on the line (the origin is a good selection) to see if it satisfies the inequality. If so, shade in everything on that side of the line. If not, shade in
the opposite side.
