2. 26
3. 39
6. 78
10. 130
12. 156

Answer 1

To determine if the quantities in the data table are in a proportional relationship, we can compare the ratios of the quantities:

26/2 = 13
39/3 = 13
78/6 = 13
130/10 = 13
156/12 = 13

Since all the ratios are equal to 13, the quantities are in a proportional relationship.
