1. Explain the difference between using a solid line and a dashed line when graphing linear inequalities. Provide an example of each.
2. Graph the inequality y > 2x - 5 on a coordinate plane. Describe the steps you took to graph it and the area that represents the solution set.
3. Given the inequality y ≤ -3x + 4, identify the y-intercept and slope. Then, graph the inequality and shade the appropriate region.
