Graphing Two-Step Inequalities on a Number Line

The video tutorial covers solving two-step equations and inequalities, emphasizing the use of inverse operations. It explains the key difference when dealing with inequalities, particularly when multiplying or dividing by negative values, which requires flipping the inequality sign. The tutorial also demonstrates how to graph inequalities on a number line and provides practice problems to reinforce the concepts.

What is the main difference between solving a two-step equation and a two-step inequality?

• The type of operations used

• The number of steps involved

• The use of variables

• The need to flip the inequality sign when multiplying or dividing by a negative number

What is the first step in solving a two-step equation?

• Divide both sides by a constant

• Add a constant to both sides

• Multiply both sides by a constant

• Identify the operations applied to the variable
