Line function
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.
[ixample] Draw perpendiculars from point (2,0) on the x-axis to its inter
section with the graph for y = 3x. Then draw a line from the point
of intersection to the y-axis.
The range values for the graph are as follows:
Xmin : - 2 Ymin : - 2
Xmax : 5 Ymax : 10
Xscl : 1 Yscl : 2
Clear the graph display and draw the graph for y = 3x.
