Brent is trying to figure out the relationship between the number of times his friends post on social media and their grade point
averages. He records the collected data on a scatter plot. Which of the linear functions best models the line of best fit? What does the
slope in the equation represent?
A)
y = 0.004x - 4; the average number of posts per friend
B)
y=-0.5x - 4; the amount of decrease in the GPA for each post
C)
y = 0.05x - 4; the amount of increase in the GPA for each post
D)
y = -0.004x + 4; the amount of decrease in the GPA for each post
