Solving and graphing a linear inequality with greater than or equal to ex 2

The video tutorial demonstrates how to solve and graph a linear inequality. It begins by treating the inequality as an equation and using inverse operations to isolate the variable. Once solved, the solution is graphed on a number line, highlighting the importance of testing points to confirm the solution set. The tutorial emphasizes understanding the inequality symbol and its impact on the graph.
