or a stationary body, the displacement time graph is a straight line parallel to the time axis.The slope of the lineis zero that indicates the velocity of the body is zero.


For a body moving with constant velocity, the displacement time graph is a straight line inclined at any angle from the time axis. If the slope is more that means the velocity of the body is more and if the slope is less it indicated the velocity of the body is less because the body moving with constant velocity says that the acceleration of the body is zero.


For a body moving with non-uniform velocity means that the displacement of the body covers in equal of interval of time is increasing, then the displacement time graph is a curved line tells that the velocity is increasing. 

If we draw the tangent at several points on the graph, we observe that as the time increases the slope of the tangent also increases. Increasing slope shows that the velocity is not uniform and the motion is accelerated.
