Systems of Linear Inequalities (Day 3)
After two challenge problems, students match graphs to systems of inequalities in a Desmos activity, build systems that meet given conditions, and sort graphs, inequalities, and types of solutions. The activity ends with an analysis question and a final challenge, and students finish with spiraling practice.
