To get a feel for the relationship between the month and the average high temperatures, the data is plotted on the following scatter plot. On a coordinate plane, points curve up and then down.
If the plot was extended to a two year period with 1 = Jan of the first year, 12 = Dec of the first year, 13 = Jan of the second year, 24 = Dec of the second year, describe the plot with the additional information.
