Understanding and Graphing One-Step Multiplication Inequalities

In this video, Mr. J explains how to solve and graph one-step multiplication inequalities. He emphasizes the importance of isolating the variable using inverse operations and highlights the need to flip the inequality symbol when multiplying or dividing by a negative number. The video includes two examples: solving 5Y < 40 and -33 >= -11M, demonstrating how to graph the solutions on a number line. Mr. J also provides tips on checking solutions and rewriting inequalities for easier understanding.

What is the first step in solving a one-step multiplication inequality?

• Use inverse operations to isolate the variable

• Add a constant to both sides

• Multiply both sides by zero

• Subtract a constant from both sides
