An assortment of fresh produce and other foods A scatterplot with points that generally have higher y-values when they also have higher x-values. There is a horizontal line at approximately y = 7.5. A scatterplot with points that generally have higher y-values when they also have higher x-values. There is a horizontal line at approximately y = 7.5. There is also a sloped line extending from approximately (0, 0) to approximately (12, 15). A scatterplot with points that generally have higher y-values when they also have higher x-values. There is a sloped line extending from approximately (0, 0) to approximately (12, 15). A scatterplot with points clustered close to the line. A scatterplot with points clustered somewhat close to the line. A graph numbered in increments of 0.5 on the x-axis There is a point mu at approximately 1.2. The graph has a negative exponential slope; at 0.0, the y-value is very high and then the slope drops very quickly as x-values increase.
