This Instructional Activity is a part of the Lesson 15, Unit 6, Grade 7. In the previous activity, students saw that solving the equation associated with an inequality gives a boundary point that separates values that make the inequality true from values that make the inequality false. This activity builds on that understanding to solidify a process for solving inequalities: first solve the associated equation to find the boundary point, then test a value to determine on which side of that boundary the solutions lie. The first two questions offer more scaffolding, and the last two questions simply give an inequality and ask students to solve and graph.
