Exploring Linear Systems

In the applet below, note the system of equations displayed. [br][br][b][color=#ff00ff]One equation is displayed in pink.[/color][/b][br][color=#9900ff][b]The other equation is displayed in purple. [/b][/color] [br][br][b]Directions: [/b][br][br][color=#ff00ff][b]1) Move the pink points (of the pink line) so that this pink line becomes the graph of the pink [br] equation displayed. (You'll get confirmation once you've done this correctly.) [/b][/color][br][br][color=#9900ff][b]2) Move the purple points (of the purple line) so that this purple line becomes the graph of the [br] purple equation displayed. (You'll also get confirmation once you've done this correctly.) [/b][br][/color][br][b]3)[/b] [b]Enter the respective [i]x[/i]- and [i]y-[/i] coordinates of the solution to this system of equations. [br] If you enter this correctly, the applet will confirm this. [/b][br][br][color=#0000ff][i]Repeat this process as many times as you need in order to master this concept! Answer the question below once you have played with this applet several times.[br][/i][/color][br][br]
