Define an Equation

Step Six

Tap No Equation Selected next to the red square.
Select New....
The screen will show y=.
Use the stylus to finish the equation to read y=x+2.
Tap OK.

 

Step Seven

It is easy to confuse the variable x with the multiplication sign x.

The variable is in the top selection area and the multiplication sign is in the lower selection area with numbers and other operation signs.

 

Step Eight

As soon as you tap OK, you will be able to view the graph.

 

Now that you have defined an equation and it is displayed on
the graph, let's think about what the graph shows.
Go to: view graph.
