Units Crossed by a Line Segment
Date: 2/2/96 at 15:22:52 From: Anonymous Subject: Patterns in graphs I got this problem at school. I've tried everything I can think of, and I just can't get it: If you connect (0,0) to (5,3) with a line segment, it goes through seven unit squares. If you connect (0,0) to (p,q) where p and q are positive whole numbers, how many squares do you go through?

The answer has to do with a right triangle and the Pythagorean theorem. Can you figure it out from here? Be sure to write us if you need more help! -Doctor Jodi, The Math Forum
