An equation was created for the line of best fit from the actual enrollment data. it was used to predict the dance studio enrollment values shown in the table below:

enrollment
month january february march april may june
acutal 12 14 14 13 16 14
predicted 8 15 15 12 17 15
residual −1 −1 1 −1 −1

analyze the data. determine whether the equation that produced the predicted values represents a good line of best fit
