The implied powers of Congress is, for the most part, granted by which part of the Constitution?

Implied powers are not stated directly in the Constitution. They derive from the right of Congress to make all laws "necessary and proper" to carry out its enumerated powers. Located at the end of Article I, Section 8, this sentence is often called the elastic clause because it stretches the authority of Congress.

Not stated directly in the constitution, but Congress made all laws "necessary and proper."
