Identifying Proportional And Non-Proportional Relationships In Tables

Students examine situations to decide whether two quantities are proportional to each other by checking for a constant multiple between measures of 𝑥 and measures of 𝑦 when given in a table. Describe the relationship between the amount of money earned and the number of hours worked in this example. A proportional relationship exists because when every measure of time is multiplied by the same number, the corresponding measures of pay are obtained.
