Assignment: lines of best fit investigation data is shown from a random selection of bamboo plants on a bamboo farm. the number of days since the plant appeared above the soil and the height of the plant are shown. days since bamboo plant appeared above soil height of bamboo plant in centimeters days since bamboo plant appeared above soil height of bamboo plant in centimeters 2 6.5 10 35.2 12 39.9 8 26.4 5 18.5 17 59.4 7 26.6 26 91.3 23 83.1 28 95.0 15 52.4 13 45.4 32 110.1 10 35.8 18 65.0 15 52.7 part a create a clearly labeled scatter plot that shows the relationship between the number of days since the plant appeared above the soil and the height of the plant. draw a trend line on the scatter plot to represent the data. 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? y = 3.5x + 0.7 2. 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. y= 3.5 (40) + 0.7 y= 140 + 0.7 y= 140.7
