TeX ⊂ LaTeX?

What is the relationship between TeX and LaTeX?
I thought LaTeX was a set of macros built upon TeX, making LaTeX a superset of TeX. But I've found, for example, that \eqalign does not exist when I run my TeX file through LaTeX (I'm using MiKTeX).
So much for the superset theory. Is there a succinct way of stating the relationship between TeX and LaTeX?

I've always wondered if foldoc online dictionary of computing which I always thought was cool, though I'm not a coder, would help with this kind of question.

Best answer: LaTeX is a set of macros built atop TeX.
"Plain TeX" is also a set of macros built atop TeX.
LaTeX and Plain TeX do not overlap perfectly, as you found.

Great find Blazecock Pileon.

Response by poster: OK, thanks, I think I've got it now.
Part of my confusion was the fact that Plain TeX, despite its name strongly implying the most unadorned version, is not the lowest level TeX.
So if I understand correctly, Plain TeX and LaTeX are both built upon TeX; LaTeX is not built on top of Plain TeX, but includes many of the same macros as Plain TeX. Agreed?

Additionally, it seems that the \eqalign macro was specifically removed from LaTeX. See, for instance, these files apparently designed to make the \eqalign macro available in LaTeX documents (see the comments for a little info regarding the original removal of \eqalign, and usage info).

That's correct.
