Deceleration.

Many have answered "deceleration" which is probably what you're looking for, but a negative acceleration doesn't necessarily mean something is slowing down.
When a ball is dropped, we often use a negative acceleration to denote the fact that it is accelerating in the downward direction. It is, however, speeding up.
I would say that an object slowing down is decelerating, but I wouldn't say an object decelerating necessarily has a negative acceleration.
Negative acceleration really means accelerating in the negative direction. Maybe you can get a bonus for pointing this out.

In fact you can call it decelleration but most Physicists would call it "Retardation".
See the link for all the descriptions.

they all got to it first, it's decceleration. Physics is fun isn't it?
