Help students connect inequalities → systems with this Algebra I, Regents-style lesson. Learners start by solving/graphing single inequalities (number line & coordinate plane) and progress to graphing systems of linear inequalities, emphasizing dashed vs. solid boundaries, when to flip the sign, above/below shading, use of a test point, and identifying the overlap region. Perfect for whole-class instruction, review, or homework—plus annotated solutions so students can self-check or study
