A guidance counselor wants to determine if there is a relationship between a student’s number of absences, x, and their grade point average (GPA), y. The data that were collected are displayed in the scatterplot and the least-squares regression line was calculated. One student with 2 absences has a GPA of 1.8. This point is circled on the graph.
What effect does the circled point have on the slope and y-intercept of the least-squares regression line?
This point will increase the value of the slope and increase the value of the y-intercept.
This point will increase the value of the slope and decrease the value of the y-intercept.
This point will decrease the value of the slope and increase the value of the y-intercept.
This point will decrease the value of the slope and decrease the value of the y-intercept.
