Graph Real-World Scenarios

The video tutorial explains how to represent and graph inequalities on a number line using open and closed circles. It covers the symbols for less than, greater than, less than or equal to, and greater than or equal to. The tutorial provides examples of graphing inequalities and applies these concepts to real-world scenarios, such as the cost of a baseball bat and saving money. Key points include using open circles for strict inequalities and closed circles for inclusive inequalities.
