Learn how to solve a multi step inequality and graph the solution

The video tutorial demonstrates how to solve and graph a linear inequality. It begins with simplifying the inequality using the distributive property, then progresses to solving a two-step inequality. The tutorial emphasizes the importance of switching the inequality sign when dividing by a negative number. Finally, it shows how to graph the solution on a number line and verify the solution by testing points.

How do you represent the solution on a number line based on the inequality?

What is the significance of testing points in relation to the solution of the inequality?
