Part B

1. Which of the following lines of best fit represent the data if x is the number of days since the plant appeared and y is the height of the plant?

A.y = -3.5x + 0.7

B.y = -0.7x + 3.5

C.y = 0.7x + 3.5

D.y = 3.5x + 0.7

1. Explain why your choice of equations best fits the data. Explain what the slope and y-intercept of the line of best fit mean about the bamboo plants.

Part C

Use the line of best fit chosen in part B to predict the height of a bamboo plant 40 days after appearing above the soil. Show your work.
