Homework Help: Slope question?

  1. Feb 15, 2009 #1
    1. The problem statement, all variables and given/known data
    What can you conclude about average slope between two points and the slopes of the individual line segments on which the points lie?


    2. Relevant equations



    3. The attempt at a solution
    I thought that the average slope slope numerical answer is in between the slopes of the two points but the question is worth two marks so there must be another fact to it.

    I think that what they are trying to get at is this:

    Given any curve between two points, how does the average value of the slope compare to the slope that would be found by drawing a straight line between the points.

    Hint: If it is known that bob runs 5km north in one hour, with no knowledge about his speed or direction at any time within that hour, can we still conclude something about his average velocity?
