Reader Input on Slope Post

A longtime reader of Turtle Talk, Jeff LeMieux, of Oak Harbor, WA, sent in a suggestion based on my post yesterday about positive and negative slope. Jeff found a way to help students remember not only positive and negative slope, but also the infinite slope of vertical lines, and the 0 slope of horizontal lines … all using the letter “N.”

This is clearly a situation where the picture speaks louder than words, so I’ll just let Jeff’s submitted picture do the talking.By the way, you can see this image much better if you double-click it.

Thanks for thinking this up and sharing it, Jeff
