In this lesson, the instructor teaches how to solve and graph linear inequalities on a number line. The lesson covers different approaches for solving these inequalities, including multiplying both sides by the reciprocal or by the least common denominator. It is important to remember that if you multiply or divide by a negative number, you must switch the inequality symbol. The instructor also emphasizes the importance of checking the solutions to ensure they are valid.
