Unit 7, Lesson 9# Solutions of Inequalities

Open Up Resources 55 min(s)

Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Recognize that inequalities of the form or have infinitely many solutions; represent solutions of such inequalities on number line diagrams. Use substitution to determine whether a given number in a specified set makes an equation or inequality true. Students can explain what it means for a number to be a solution to an inequality.
