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).

Sketch a straight line segment between these points.

What are the rise, run and slope of this segment?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
Rise=30m/s
Run=5 s
Slope= 6m/s/s

What is the area of the graph beneath this segment?

I do not have a program on my computer that does graphs, so I drew them out, which is why they are not included.
You haven't shown your reasoning, and you should be probably be sketching these graphs by hand (quicker and more tangible). The program will of course be useful for more complex graphs, or graphs with larger data sets.
In any case your second result is way off (first result is good). Please submit a revision for the second, as indicated below.
