This section describes how to use each of the commands on the [Sketch] menu. Note that all
of the procedures in this section are performed in the Graph & Table application, which you

u To plot a point on the Graph window
(1) While the Graph window is active, tap [Analysis], [Sketch], and then [Plot].
(2) Tap the location on the Graph window where you want to plot a point.
• Instead of tapping the Graph window, you could also use the keypad to specify the
coordinates of the point. Pressing a number key displays a dialog box for inputting
coordinates. The value of the key you just pressed is input for the
x -coordinate. After inputting values for the x - and y -coordinates, tap [OK]
to plot the point at the location you specified.
