1. Explain the steps you would take to graph the inequality 3x + 2y ≀ 6. Include how you would determine the type of line to draw and how you would identify the solution region.

2. Given the inequality y > 1/2x + 3, describe how you would graph this inequality. What does the shaded region represent in this context?

3. Write an inequality that represents the following real-world scenario: A school has a budget of $500 for a field trip. Each student ticket costs $15. How would you express the number of students (x) that can attend the trip?
