Question

For an experiment, a student measures the growth of a plant on a weekly basis and determines that the growth of the plant can be modeled by the equation

y= 1.5x + 6, where x represents the number of weeks and y represents the height of the plant in inches. Which statement is true?

A. The plant grows about 6 inches per weeks
B. The data was collected for 1.5 weeks
C. The height of the plant at the beginning of the experiment was 6 inches
D. The height of the plant at the end of the experiment was 1.5 inches
