k Rectangular Coordinate Graph
Inputting the Graph command in the Run-Matrix mode enables drawing of rectangular
coordinate graphs.
1. From the Main Menu, enter the Run-Matrix mode.
2. On the Setup screen, change “Input/Output” setting to “Linear”.
3. Configure V-Window settings.
4. Input the commands for drawing the rectangular coordinate graph.
5. Input the function.
Example Graph
y = 2x

+ 3x – 4.
Use the following V-Window settings.
Xmin = –5, Xmax = 5, Xscale = 2
Ymin = –10, Ymax = 10, Yscale = 5
