I would say that this geometric approach is much more intuitive since students can easily count squares while others had trouble solving for x or understanding what the x that they solved for represented. The geometric approach was much nicer since it segued into "rise-over-run" for the slope. Just count the rise over run from start to midpoint, then do it again to get to the endpoint. | |
