MIT. is trying to pick aquatic plants to put in his lake. These plants add oxygen to the water, which is necessary for the survival
of Mr. K's fish. He takes two different species of plant (Plant A
and Plant B) and puts them at different depths in the lake. He then
measures how many oxygen bubbles each plant produces per
minute at each depth. Using the following data, answer the
questions below and then graph the data.
