The problem:

A ball is moving at 10 cm/s when clock time is 4 seconds, and at 40 cm/s when clock time is 9 seconds.

• Sketch a v vs. t graph and represent these two events by the points (4 sec, 10 cm/s) and (9 s, 40 cm/s).

->->->->->->->->->->->-> answer/question/discussion:

• Sketch a straight line segment between these points.

->->->->->->->->->->->-> answer/question/discussion:

• What are the rise, run and slope of this segment?

The rise is 30, the run is 5. The slope is 6.
