Question

Does the data in this table represent a proportional relationship?
Time 1
Water used 5
Time 2
Water used 10
Time 3
Water used 15
Time 7
Water used 35
Time 10
Water used 50

Answer 1

is it because the ratios of all data points are equivalent or because the unit rate is 1

Answer 2

Yes, the data in this table represents a proportional relationship. As the time increases, the water used also increases, and the ratio between time and water used remains constant.

Answer 3

It is because the ratios of all data points are equivalent. In this case, if we divide the water used by the time for each data point, we get a consistent ratio of 5/1, indicating a proportional relationship. The unit rate of 1 is not necessary for a relationship to be proportional; it is the consistency in the ratio that determines proportionality.
