When solving a system of linear inequalities graphically we will follow these steps:
1. Solve the inequality for y.
2. Treat the inequality as a linear equation and graph the line as either a solid line or a
dashed line depending on the inequality sign.
a. If the inequality sign does not contain an equals sign (< or >) then draw the line as
a dashed line.
b. If the inequality sign does have an equals sign (≤ or ≥) then draw the line as a
solid line.
3. Shade the region that satisfies the inequality
4. Repeat steps 1 – 3 for each inequality
5. The solution set will be the overlapped region of all the inequalities .
