Residual = Observed Value - Predicted Value
A residual plot is a graph that shows the residual values in the vertical axis and the independent variable or values of x in the horizontal axis. So the coordinates would be (x, corresponding residual of x)
The points in a residual plot of the data based on the table will be:
(1,-0.4)
(2,0,7)
(3,-0.2)
(4,-0.6)
