Don't understand what I have to do in order to find out what I have to plot.

These are the values in Kamil’s data set.

(1, 22), (3, 18), (5,14), (6, 13), (8,5)

Kamil determined the equation of a linear regression line and determined that these are the predicted values, to the nearest integer.

(1, 23), (3, 18), (5,14), (6, 11), (8,7)
