Answer: Graph A represents the number of roommates, Graph B represents the number of free hours, and Graph C represents the cost of tuition
Step-by-step explanation: We know that the x axis is the number of courses. We can solve this by thinking about it as a real world issue. Think about it: since B has a downwards slope, doesn't it make sense for it to represent the number of free hours? Wouldn't taking more classes affect the amount of time you have? And if C is the cost of tuition, then wouldn't it make sense that it has a rising slope? Hope this helps
