Exercise

Fit a line

Continuing from the previous exercise:

Assume that xs and ys contain income codes and daily vegetable consumption, respectively, and
res contains the results of a simple linear regression of ys onto xs.

Now, you're going to compute the line of best fit. NumPy has been imported for you as np.
