Determine whether true or false: A straight line on the distance-time graph indicates that the object is moving at a constant speed.

A distance-time graph depicts how far an object has travelled in a given amount of time. The motion is uniform if the distance-time graph is a straight line. 

If an object's distance-time graph is provided, the speed may be computed using the slope of the graph. If the slope is a straight line it indicates that the item is moving at a constant speed.
