Understanding Discrete and Continuous Graphs

This lesson explains the difference between discrete and continuous variables in equations by examining their solutions on graphs. It uses examples of Josie's DVD purchases to illustrate discrete graphs and Brian's game time to demonstrate continuous graphs. Discrete graphs have isolated points, while continuous graphs have connected points. The lesson emphasizes understanding when to connect points based on the context of the problem.

Explain the significance of choosing integer values for x when graphing a linear equation.
