fit. The data point is 4.5 units below the line of best fit. The line of best fit is not appropriate to the data. The line of best fit has a slope of –4.5.
The data point is 4.5 units below the line of best fit
Explanation;
-A residual value of –4.5 mean in reference to the line of best fit means that the data point is 4.5 units below the line of best fit.
