Closing:
1.) What points are always on the graph of two quantities that are proportional to each other?
2.) How can you use the unit rate to create a table, equation, or graph of a relationship of two quantities that are proportional to each other?
3.) How can you identify the unit rate from a table, equation, or graph?
