Answer 1

The correct response is:

Gregory’s graph is correct because it shows 1.5 inches of growth every two weeks.

Since the plant grows 1.5 inches every two weeks, it is important to express the growth on a weekly basis. The growth rate per week would be half of 1.5 inches, which is 0.75 inches per week. If the graph correctly represents the plant's growth as 0.75 inches per week, then it is accurate. However, if the graph shows 1.5 inches of growth as a weekly rate, that would be incorrect.

Since the response options provided contain errors, the option "Gregory’s graph is correct because it shows 1.5 inches of growth every two weeks" is the most accurate, given it acknowledges the correct amount of growth over the specified time.
