Right. From "The Penguin Desk Encyclopedia of Science and Mathematics":

"Linear (algebra) An equation or function of the form ax + by + c = 0
or f(x) = mx +b is called linear because its graph is a line. This has
been generalized to a concept called linear combination, which is the
sum of 2 or more entities with each multiplied by some number (with not
all numbers being 0). Linear combinations of vectors, equations, and
functions are commonly employed."

I think that definition is broad enough to cover the representations I
made in my postings.

You're right in a certain mathematical sense, but that definition
isn't correct, as Roy pointed out, in defining superposition.
