This is a scatter plot with the emissions rate in grams per kilogram on the y-axis and fuel moisture on the x-axis. The co-ordinates of each point are as follows: (9.5, 2.97), (12, 2.33), (16, 3.75), (17, 4.89), (17, 4.63), (18, 4.22), (18, 4.25), (19, 3.63), (40, 11.21). A line of best fit, which has a positive gradient, is drawn through these points.
