Promoting Understanding of Linear Equations with the Median Slope Algorithm

Michael Edwards 

February 2005, Volume 98, Issue 6, Page 414

Abstract:
An author-invented algorithm, the median slope, to help students understand  the basics of linear equations before and without using the graphing calculator. Unlike calculator-based linear regression techniques, the steps that underlie the median slope algorithm are entirely accessible to first-year algebra students. Step by step examples are given as well as directions for programming the median slope algorithm into the graphing calculator.
