Poor economy. I took a test via quizlet
Answer:
The Clause gives Congress the authority to use powers not explicitly named in the Constitution, if they are necessary in order to perform its responsibilities as outlined in the Constitution. In other words, Congress may do whatever is “necessary and proper” to do its job.
Okay the main difference is "power" is what they can do, "Authority" is was power they already have.
