Han creates a scatter plot that displays the relationship between the number of items sold, \(x\), and the total revenue, \(y\), in dollars. Han creates a line of best fit and finds that the residual for the point \((13, 930)\) is -40. Interpret the meaning of -40 in the context of the problem.

The line of best fit for a data set is \(y = 1.1x + 3.4\). Find the residual for each of the coordinate pairs, \((x,y)\).

1. \((5, 8.8)\)
2. \((2.5, 5.95)\)
3. \((0, 3.72)\)
4. \((1.5, 5.05)\)
5. \((\text{-}3, 0)\)
6. \((\text{-}5, \text{-}4.86)\)

Plots of the residuals for four different models of the same data set are displayed. Which of the following represents the plot of the residuals from a model that fits its data best?
