A scatter plot with line of fit and residuals is shown. A scatter plot contains ordered pairs 1,5 and 2,3 and 3,6 and 4,8 and 5,4 and 6,4 and 7,7 and 8,8 and 9.6. A line of fit is drawn through ordered pairs 0,4 and 9,7. Segments drawn from the ordered pairs to the line of fit measure 0.667 and 1 and 2.667 and 0.667 and 1.333 and negative 1.667 and negative 1.667 and negative 2 and negative 1. Explain if the line of fit is an appropriate model for the data. The line of fit is not appropriate because the sum of the residuals is zero. The line of fit is appropriate because there are 5 positive residuals and 4 negative residuals. The line of fit is appropriate because the sum of the residuals is zero. The line of fit is not appropriate because there are 5 positive residuals and 4 negative residuals
