Solving Inequalities in Two Variables
Grade 9•45 minutes•HSA.CED.A.3; HSA.REI.D.12
Learning Objective
I can use graphing technology to find the solution to a two-variable inequality. When given inequalities, graphs, and descriptions that represent the constraints in a situation, I can connect the different representations and interpret them in terms of the situation.
Practice Questions
This lesson includes 6 practice questions to reinforce learning.

1. Explain the process of isolating y in the inequality -4x - 7y < 4. What is the first step you would take?
2. After isolating y in the inequality -4x - 7y < 4, what does the inequality become? Write the new inequality.
3. Describe how to graph the inequality y > -2x - 4. What type of line would you draw, and why?
