(b) Use a straightedge to sketch the line that you think best fits the data.
(c) Find an equation for the line you sketched in part (b). (Use P, = (10, 64) and P2 = (18, 96) to form the line.)
V =
(d) Use the equation in part (c) to estimate the average test score for a person with an average quiz score of 17. (Round your answer to the nearest whole number.)
(e) The instructor adds 4 points to the average test score of each student in the class. Describe the changes in the positions of the plotted points and the change in the equation of the line.
Each point will shift four units to the right, so the best-fitting line will move four units to the right.
Each point will shift four units to the left, so the best-fitting line will move four units to the left.
O Each point will shift four units upward, so the best-fitting line will move four units upward.
O Each point will shift four units upward, so the best-fitting line will move four units downward.
O Each point will shift four units downward, so the best-fitting line will move four units downward.
