Question

The displacement time graph of a body is parallel to time axis what will you infer about the velocity of the body

Answer 1

hy
___

the body is moving with constant velocity or uniform velocity that is with the same speed .time is increasing but the speed if the body is constant!!

hope helped!!

Answer 2

The velocity of the object is the slope of the displacement time graph of that object. But since the graph makes 0° with the x-axis(time) being parallel thus slope, that is tan theta = 0
And, hence the velocity of the object is zero and this means that the object is at rest and does not change it's position with passage of time.
