MathIsFun.com's linear equation Flash applet

When I teach regression, I usually introduce the regression line by reminding my students of the long-ago days of algebra class and graph paper and rulers.

MathIsFun.com has created an interactive applet that mimics the graph paper and allows users to adjust the y-intercept and the slope. This is a slightly fancier, more high-tech way to get your students thinking about the linear equation and then fitting that old knowledge into the new concept of regression.

Use the bars to adjust slope and y-intercept as a quick linear equation primer before teaching regression
