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`

.

Instructions

**100 XP**

- Set
`fx`

to the minimum and maximum of`xs`

, stored in a NumPy array. - Set
`fy`

to the points on the fitted line that correspond to the`fx`

.
