I'm in a Management Science class going through some probability and
statistics stuff. I'm trying to create a graph that imitates the one
in the book. We're using QM for Windows, but I wanted to something
simple in Excel in order to understand the problems.

I have all the data, but figuring out how to set it up in Excel is
what's killing me.

Two categories:

Receivers with a line drawn from point 0,20 to 40,0
CD players with a line drawn from point 60,0 to 0,20

I want the lines to originate and end on the axis themselves, excel
wants to place them in the middle of the entire graph.

The other thing is I want to enter individual points as above and not
do something like 40,20.

Any help would be appreciated.
