what is meant bynon proportional linear relationship?

bobpursley,
That is an idiotic term invented by math teachers.
Here are examples...
y=3x is a linear equation, proportional.
y=3x2 is a linear equation, nonproportional.
any linear equation is of the form
y=mx+b
When b is zero, it is a proportional linear equation.
When b is nonzero, it is a "nonproportional" linear equation according to that thinking.
Shakespear wrote Much Ado about nothing, as I recall, but is being reformed here.

Reiny,
Loved your response!
I always followed one of the sayings of Albert Einstein, who, loosely stated, said
"Everything should be made as simple as possible, but ...
not too simple."
