Graphing Linear Inequalities: Modeling Constraints and Solutions

The video tutorial explains how to represent solutions and constraints to linear inequalities by graphing. It uses a practical example involving postage stamps to illustrate the concept. The tutorial covers setting up inequalities, graphing them, and understanding constraints such as positive and whole numbers. It also discusses finding integer solutions and ensuring the constraints are met.
