Inequalities and Graph Interpretation

The video tutorial covers the application of linear inequalities in a real-world context, focusing on setting up and graphing inequalities based on budget constraints. It explains how to find x and y intercepts, graph the inequality, and identify solutions within the shaded region. The tutorial also includes an example to analyze symbols and verify solutions, emphasizing the importance of understanding the inequality's graphical representation.
