You are given the following input-output (x, y) pairs, sorted according to the input: (8.4, 89.0), (9.4, 81.0), (9.9, 93.1), (11.2, 116.3). For the above data, please give an example of regression that has a coeffi- cient of determination, i.e., R2, less than 0. Give the predictions from your regression and show your calculation steps and the R2 value. You may use Python to do the actual calculations.
