In оrder tо find the line y = m x + b thаt best fits the dаtа shоwn below, we can use the Least Squares method to solve for the best possible values for b and m. x -1 0 1 2 3 4 y 0 0 0 2 1 2 Do this by (a.) first writing the design matrix A for the unsolvable system A b m = y → , where y → = 0 0 0 2 1 2 . Then (b.) use the "normal equation" for this problem to compute the matrix C for which C b m = y ^ . Finally, (c.) solve this equation to obtain a solution b m . It might help to graph your line and the data in Desmos to confirm for yourself that you didn't make a mistake.
