do i make a trigger that subtracts a certain amounts of points from health of a unit?

Drezman, c'mon, that's an obvious one. Unit - Set Life, and use Arithmetic.

Set Life of (triggering unit) to Life of (triggering unit) - x

Spend some time learning the trigger actions, you'll discover a lot on your own without waiting for somebody else to answer you.
