Read the scenario. A tree grows 3 feet every year. How does this scenario show one quantity changing at a constant rate relative to another?

A constant rate means the quantity changes by the same amount over equal time intervals. The tree grows 3 feet every year, so its height increases by the same 3 feet each year. Choice D, “The height of the tree increases by the same amount each year,” describes this constant rate.
