Acceleration doesn't mean "speeding up". It only means that the speed or direction of motion,
or both, are changing.
Speeding up is positive acceleration in the direction you're moving.
Slowing down is negative acceleration in the direction you're moving, or positive acceleration in the
opposite direction.

An object that is accelerating may be?
An object that is accelerating may be slowing down, gaining speed, and changing direction.
An object that is accelerating maybe slowing down or speeding up?
yes the acceleration can take a negative value. for example an object with an accleration of -2 ms-2 would be slowing down. However this is normally called deceleration.
A negative slope on the velocity vs. time graph indicates that the object is not accelerating.?
It means the object is decelerating - slowing down rather than speeding up. You can think of it as negative acceleration.
How can you tell visually if the forces on an object are balanced?
If the object is not moving, or is traveling at a constant velocity, all forces acting on the object are equal and opposite to each other. If the object is accelerating (speeding up, slowing down, or changing direction) the forces are not balanced.
How can a car slowing down also be accelerating?
In physics, "acceleration" means there is a change of velocity.

Is an object that is slowing down accelerating?
Acceleration is defined as change of velocity so the answer to the question is yes. Negative acceleration (ie when velocity is decreasing) is called deceleration.

If the object is not moving, or is traveling at a constant velocity, all forces acting on the object are equal and opposite to each other. If the object is accelerating (speeding up, slowing down, or changing direction) the forces are not balanced.
Is a car accelerating when it is coming to a stop at a light?
No, when anything is slowing down it is decelerating.

When an object is slowing down it is not at what?
It is not at rest.
How can a car slowing down also be accelerating?
In physics, "acceleration" means there is a change of velocity.
When an object slows down it has no acceleration?
When an object slows down it is still accelerating.
When acceleration and velocity vectors are pointing in opposite directions the object is?
This would indicate negative acceleration, which would mean that the object in question is speeding up.
When is the car decelerating?
It is decelerating any time it is not accelerating or is stopped. Decelerating means slowing down.
