LESSON 5: Identifying Proportional and Non-Proportional Relationships in Graphs Dr. Basta Isaiah sold candy bars to help raise money for his scouting troop. The table shows the amount of candy he sold to the money he received. Is the amount of candy bars sold proportional to the money Isaiah received? How do you know?

LESSON 5: Identifying Proportional and Non-Proportional Relationships in Graphs Dr. Basta2 Characteristics of graphs of proportional relationships: Points lie in a straight line. Line goes through the origin. What is the origin and where is it located? The intersection of the x and y axis, at the ordered pair (0,0).

LESSON 5: Identifying Proportional and Non-Proportional Relationships in Graphs Dr. Basta3 1. The following table gives the number of people picking strawberries in a field and the corresponding number of hours that these people worked picking strawberries. Graph the table. Does the graph represent two quantities that are proportional to each other? Explain why or why not.
