Part III: Assume Kyle and Caitlyn were extremely accurate and the correlation coefficient is r = 0.99. Find the line of best fit to model the data. Step 1: Use the formula to find the slope of the line of best fit. Caitlyn already calculated the standard deviation of the y-values as sy = 7.32. (4 points) Step 2: Find the y-intercept using the formula a = y − bx. (2 points)

Step 1: Use the formula to find the slope of the line of best fit. Caitlyn already calculated the standard deviation of the y-values as sy = 7.32. (4 points) Step 2: Find the y-intercept using the formula a = y − bx. (2 points) Step 3: Write the line of best fit, , to model the data. Replace y and x with the variables used in the experiment and on the graph. (2 points) Part IV: What do the slope and the y-intercept tell you about the variables in the experiment? (2 points) Part V: Use the line of best fit from Part III, Step 3 to predict how far the spring will stretch with a mass of 67 grams. (1 point) Copyright © 2015 Apex Learning Inc.
