Lyrics and Performance by Vicki Young
Melody: "You Are My Sunshine"

The other day, dear, as I was graphing,

Instead of one line there were two!

I was perplexed until I realized

My teacher would tell me what to do.


When you have two lines, it's called a system,

And there are three outcomes you'll view:

They're parallel lines or they're the same line

Or they cross in one point that is true.
