#### Answer:

Boyle's Law states both that as volume increases pressure decreases and that as pressure increases volume decreases.

#### Explanation:

Boyle's Law states that pressure and volume are inversely proportional, but also assumes that the material is a confined gas (so no amount of gas increases or decreases) and the temperature remains steady.

Mathematically, it can be stated a couple of ways:

or

And so Boyle's Law states both that as volume increases pressure decreases and that as pressure increases volume decreases.
