1. Determine whether the line is horizontal. If it is, the object is moving at a constant velocity. You can find that rate by looking at the point where the line crosses the yaxis.

The slope of the velocitytime graph is the acceleration. this is because the slope is defined as delta y/delta x. and the y is the velocity while the x is the time: delta v/ delta
