A student is assessing the correlation between the number of hours a plant receives sunlight and the height to which it grows. The table below shows the data.

Number of hours of sunlight(x): 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Height of plant in cm(y): 4, 7, 10, 13, 16, 19, 22, 25, 28, 31

(0,4) (1,7) (2,10) (3,13) (4,16) (5,19) (6,22) (7,25) (8,28) (9,31)

Questions:
1: Write a function which best fits the data.
2: What does the slope and y-intercept of the plot indicate about the plant?
