Solving Inequalities by Graphing
Answer each question using complete sentences.
1. What does a solid boundary line indicate on the graph of an inequality?
2. Which inequality symbols are used to indicate all points up to but not including the boundary line are
solutions to the inequality?
3. Explain why the solution set is shaded below the line for the graph
of 5x – 6y > 30.
4. Explain why (0, -5) is not a solution to 5x – 6y > 30.
5. Explain how y ≥ -15x + 130 should be graphed.
