Solving and graphing an inequality by dividing by negative one

The video tutorial explains how to graph inequalities by first solving for the variable. It highlights the importance of changing the inequality symbol when dividing by a negative number. The tutorial guides students through plotting points on a graph, testing these points to determine if they satisfy the inequality, and understanding the concept of open circles. It emphasizes the need to graph towards true values and clarifies the meaning of inequality symbols.
