This lesson is an introduction to linear inequalities. The instructor explains the symbols for less than, less than or equal to, greater than, and greater than or equal to. They then demonstrate how to graph true inequality statements and provide helpful tips for solving problems where the variable is on the right-hand side. The lesson also covers sandwiching a variable between two numbers and graphing those solutions.
