The screen will show y=.
Use the stylus to finish the equation to read y=x+2.
Tap OK.


Step Seven

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.
