Solving by Graphing
Solve the system by graphing.
Step 1 — Graph . The boundary line is . Because the inequality uses (strict), draw a dashed line. Test : gives , which is true, so shade the side that contains the origin.
Step 2 — Graph on the same grid. The boundary line is . Because the inequality uses (strict), draw a dashed line. Test : gives , which is false, so shade the side that does not contain the origin.
Step 3 — Identify the solution. The solution is the overlapping shaded region. The intersection point of the boundary lines is not included because both lines are dashed.
Step 4 — Verify with a test point. Choose a test point in the overlapping region and substitute it into both inequalities to confirm both are true.
