OK...if you take a contain of a certain size and fill it with air, then close it. There is a certain amount of pressure pushing up against the walls of the container. If you were to force in more air, the pressure against the walls increases. So, volume remains the same and pressure goes up. Now with that same amount of air, increase the size of the container. As volume increases, the air has more space to go and doesn't push up against the wall as much, thus the pressure goes down. So as volume increases, pressure decreases. The opposite is true as well.

Because if all other things are equal (like temperature), as one goes up, the other comes down. This is known as inverse proportionality.
