PREDICT THE MAXIMUM HEIGHT OF A BICYCLE THAT WEIGHS 21.5 pounds, ALL OTHER THINGS REMAINING CONSTANT.

here is the data provided

WEIGHT, HEIGHT

19.5 10.3
20 10.25
20.5 10.2
21 10.1
22 9.85

What have you been taught to solve these types of problems? Are you supposed to fit "least-square" line through these points?
