Create and Graph Relationships with Linear Functions

The video tutorial explores how to use linear functions to model and graph relationships in a photography business context. It begins with an introduction to the concept of making money from photography, followed by a review of functions and their representation. The tutorial explains linear functions, their graphs, and the concept of slope. It provides tips on avoiding common mistakes in word problems and investigates a specific problem involving costs and profits. Finally, it demonstrates how to graph the function representing the relationship between the number of photo shoots and profit.
