Problem 1. Perform a least squares linear regression on the dataset
{(-1,–1), (0, 7), (1, 1)},
where
is some number. Find the slope, a, and intercept, b.
Note: There is only one critical point, which essentially means that it has to be the point where the
function takes its minimum. Don't worry too much about that part of the argument yet; we'll refine this
type of argument soon.
