(a) At Rest: If the distance-time graph is a straight horizontal line, it means the object is at rest. This is because the distance the object is from a certain point is not changing as time passes.

(b) Moving with Constant Speed: If the graph is a straight line inclined at an angle to the time axis (other than 90 degrees), it means the object is moving at a constant speed. This is because the distance the object is covering is increasing uniformly with time.

(c) Accelerating: If the graph is a curve that slopes upwards, it means the object is accelerating. This is because the distance the object is covering is increasing at an increasing rate as time passes.

(d) Decelerating: If the graph is a curve that slopes downwards, it means the object is decelerating. This is because the distance the object is covering is increasing at a decreasing rate as time passes.
