what are the answers to graphs of proportional relationships practice(2,14), (28,4), (42,6), (56,8),(70,10), (84, 12)

Answer 1

To determine if these points represent a proportional relationship, we need to check if the ratio of y-values to x-values is the same for each point.

Let's calculate the ratios for each set of points:

- For (2,14), the ratio is 14/2 = 7.
- For (28,4), the ratio is 4/28 = 1/7.
- For (42,6), the ratio is 6/42 = 1/7.
- For (56,8), the ratio is 8/56 = 1/7.
- For (70,10), the ratio is 10/70 = 1/7.
- For (84,12), the ratio is 12/84 = 1/7.

Since the ratio is consistent (1/7) for each set of points, we can conclude that these points represent a proportional relationship.
