Nope. You're illustrating precisely why you're failing the class.
That's _not_ the definition.

Actually from what you say here it seems pretty likely that
you do know what linear independence _is_, but the
way you're stating the definition is totally wrong. Knowing
something doesn't help much if you can't explain it
coherently. Next time you take the class try actually
_learning_ the definitions of all the important terms,
_precisely_. It _will_ help, whether you believe it or not.
