Title: Determining Proportional Relationships

Instructions: For each set of data, determine if the values are proportional or not. If they are proportional, find the constant of proportionality (k) and write the equation in the form y = kx. If they are not proportional, write “Not Proportional.”

Set 1: x | y 2 | 4 4 | 8 6 | 12 8 | 16

Set 2: x | y 3 | 9 5 | 15 7 | 21 9 | 27

Set 3: x | y 1 | 5 2 | 10 3 | 15 4 | 20

Set 4: x | y 2 | 3 4 | 6 6 | 9 8 | 12

Set 5: x | y 2 | 5 4 | 10 6 | 15 8 | 20

Set 6: x | y 1 | 3 2 | 6 3 | 9 4 | 12

Set 7: x | y 3 | 6 5 | 10 7 | 14 9 | 18

Set 8: x | y 1 | 2 2 | 4 3 | 6 4 | 8

Set 9: x | y 2 | 7 4 | 14 6 | 21 8 | 28

Set 10: x | y 3 | 12 5 | 20 7 | 28 9 | 36

Note: You can add more sets of data or modify the existing ones based on the complexity level of your class.
