Graphing Linear Equations: Question Generator (V2)

The original idea for creating this applet comes from [url=https://www.geogebra.org/stevephelps]Steve Phelps[/url]' [url=https://www.geogebra.org/m/WVGxwKKn]Graph the Line[/url] applet. [br] [br][b]Directions:[/b][br][color=#000000]1) Examine the equation shown on the right side of the screen. [/color][br]2) [b]Reposition the 2 big points so that the line is the graph of the displayed equation. [br][/b]3) Click the "Check Answer" checkbox to check. [br][b] [color=#ff00ff]If you're correct, the app will inform you.[/color] [br][/b][b] If you're not, you'll know this as well. [/b][color=#000000][br] If you're not correct, keep trying until you position the gray line correctly.[br][br][/color]4) After correctly graphing the line, click the "Generate New Line" button.
