EZ Math Movie starts out with a normal (x, y) graph visible at startup:
At startup and throughout most of the tutorials the graph has these bounds:
We will state these bounds with this type of notation: x:[10, 10], y:[10, 10] 
The top of the graph panel holds some controls and information:

To change the graph bounds, click the checkbox in the upper left corner and a drop down list of bounds will appear. Use the list and select the bounds that you would like.
The notation works this way:
After making your selection click the checkbox again to close things up and have your changes accepted. 
The following example program sets up the graph and draws a line segment and a point. Click the 'Go' button on the graph panel to see this. The details of this program will be explained in the following tutorials.
