B. Julian adds 5 laps to his swimming routine every week.
Explanation:
We are given a number of situations and we are to figure out whether which of them can be modeled by a linear function.

A. Nicole's hair grows at a rate of 1/2 in. per month.
B. Julian adds 5 laps to his swimming routine every week.
