When the pointer is at the location you want,
press
G9 to plot a point. At this time, the
pointer returns to the original point you speci-
fied (2, 2 in this example).
EXE]
Now, inputting a new coordinate value causes
the new pointer to blink without clearing the
present pointer.

The Line function makes it possible to connect two points (including the blinking
! pointer) created with the Plot function with a straight line. With this function, user
; generated lines can be added to graphs to make them easier to read.
: Draw perpendiculars from point (2,0) on the x-axis to its inter-
t section with the graph for y=3.x. Then draw a line from the point
of intersection to the y-axis.
The range values for the graph are as follows:
