[Blindmath] Question Concerning the Audio Graphing Calculator

[Sharon Clark]

Hello Everyone: 

I have a student using the Audio Graphing Calculator 3.0 from View Plus.  I
instructed the student in how to plot user defined points using the tutorial
provided; however, when the student gave their coordinates for a problem in
the textbook, the AGC would not evaluate nor show the graph.  Would someone
be able to assist me with this situation? 

When plotting the user defined points, he put in: 
Points = 3 and the following coordinate (2, 4), (3, 6), and (4, 8).  

Thank You,
Sharon
