A position-time graph is shown below: (2 points) A Position versus Time graph is shown with y-axis labeled position in centimeters up to 15 and x-axis labeled time in seconds up to 10. A straight line connects the points 0, 0 and 3, 3. A horizontal line connects points 3, 3 and 6, 3. A straight line connects 6, 3 and 10, 11.

Which statement accurately describes the speed of the object in the graph above over the 10 seconds?
Speed is decreasing.
Speed is constant.
Speed is not constant.
Object is at rest.
