    What were the values given in the dependent variable?
    Its better to use 20, 40, 60....
    or 10, 20, 30
    But I need to know the values for the y axis.
    For that graph the max y value is 230 - 240 or something so its not possible to take 20, 40, 60... or 10, 20, 30...

    The best way to take up all the space is to use 30, 60, 90...

    A mathematical Model can be wrong As it might not include other factor which are varying.
    there is a limited data on which it is based.

    Publisher as in publisher info. If they give only name then name goes there. If they give name and place, name first, then place.

    It's from June 2009, 6BI07, question 2 (b)(ii)

    I can't find a suitable scale for the y-axis; the mark scheme doesn't give any details about the scale either.
