Step Nine
Ask students questions using:
 xaxis
 yaxis
 origin
 yintercept
 xintercept
 points that fall on the line
 rise over run (if they are ready)
 slope (if they are ready)

Step Ten
Tap the stylus on the line
Cross hairs appear
The values of the x and y coordinates will display on the screen.
Two arrows appear at the bottom of the display.
Use the arrows to move along the line in either direction.


Step Eleven
Talk about the scale that works best to view this line.
What scale makes the line disappear?
What scale makes it easiest to name the xintercept?
What scale makes it easiest to name the yintercept?

Let's try changing the equation and see how that effects the graph.
Go to: change slope and yintercept.
