1. This is actually a little bit tricky. Even
though we've talked a lot about what
2. vocabulary is, sometimes it's hard to
apply it to actual situations. Let's start
3. from the bottom and work up. -100000 is
part of a term, but the term that it's
4. part of is actually -100,000x. Remember
that the term is the whole thing that's
5. going to be added to other things or
subtracted from other things. So -100000
6. on its own is not a term, so let's cross
that out. We said earlier that -100,000x
7. is a variable term as a whole, but it's
not the -100000 that makes the term a
8. variable term. It's the x that does that,
so, -100,000 itself is not a variable.
9. Constant was the word that we used for
numbers that were terms on their own,
10. things like 3 million right here. This is
something that is a term by itself that
11. has no variables as part of it. -100,000
is not standing on its own, it's
12. multiplied by x, so this is not a constant
either. That leaves us with coefficient.
13. Remember that coefficients are the number
parts of variable terms. So they are
14. numbers that are multiplied by variables
to create variable terms. I know there are
15. a lot of subtle differences involved in
this, but over time this will become a
16. much more natural feeling. Great job
working on all this vocab.
