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?

What is the area of the graph beneath this segment?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
Area = (1/2)(5* (10+40)/2)
Area = (1/2)(5*25)
Area = (1/2)(125)
Area = 62.5

Your numerical calculations are correct, but you need to include units throughout your analysis.
Can you resubmit showing the steps
(40-10)/(9-4)
30/5
6
with the proper units on each quantity?
Can you do the same for the expressions
Area = (1/2)(5* (10+40)/2)
Area = (1/2)(5*25)
Area = (1/2)(125)
Area = 62.5
