This comprehensive resource applies simultaneous equations to a real-life problem. Though the commentary starts with a graph, some home consumers may choose to begin with a table. A graph does aid learners to visualize the shift of one line to change the intersection point. This helps with discussion questions at the end. Overall, a great model that provides lots of learning.
