Solving Linear Inequalities in Algebra 2

The video tutorial covers systems of inequalities, starting with an introduction to inequalities and their symbols. It explains how to graph inequalities, emphasizing the importance of solving for y and using slope-intercept form. The tutorial includes multiple examples, demonstrating how to solve and graph inequalities, identify solution sets, and understand parallel lines. It also discusses scenarios where no solution exists. The video concludes with a review of key concepts and encourages students to practice and test their understanding.

What is the first step in solving the inequality 2y < -3x + 4?

• Add 3x to both sides

• Subtract 3x from both sides

• Multiply both sides by 2

• Divide both sides by 2
