## General Flash Grapher

This flash graphing application was created because I needed a program where I could quickly create point and line graphs while lecturing my Algebra I class. It's pretty simple to use just click a button and you can place as many points, lines, and curves on the graph as you want. Click the red X to make them all go away.
