Sample Project

 Find the unit rate for each set of data in the table.  If the unit rates are the same for each entry, then the relationship is proportional.  If the unit rates are different, then the relationship is not proportional

If a graph is showing a proportional relationship, it will:  Be a straight line  Cross through the origin of the graph
