Exploring One & Two Step Inequalities

The video tutorial covers SOL 7.13, focusing on one and two-step inequalities. It explains the differences between solving equations and inequalities, emphasizing the need to flip the inequality sign when multiplying or dividing by a negative number. The lesson includes examples, exercises, and graphing solutions on a number line. Students are encouraged to predict which inequalities require sign flipping and solve various inequalities using inverse operations.

What is the main focus of SOL 7.13?

• Solving multi-step inequalities

• Solving one and two-step linear inequalities

• Graphing quadratic equations

• Understanding polynomial functions

What must you do when you multiply or divide both sides of an inequality by a negative number?

• Flip the inequality sign

• Subtract the same number from both sides

• Keep the inequality sign the same

• Add the same number to both sides
