  1. maybe it'd be easier without all the zeros:

    1 18
    2 37
    3 48
    4 66

    y=17x comes close. The errors are

    1 +1
    2 +3
    3 +1
    4 -2

    Use your favorite regression tool for a more exact line. The best-fit line is

    y = 15.5x + 3.5

    a good calculator and grapher is at

    http://www.alcula.com/calculators/statistics/linear-regression/

    It requires at least 5 data points, though so enter 5,81 as a 5th point, since it is exactly on the line of best fit.
