    equation that best represents the line of the best fit for this set of data is:

    1) y = 15x

    x y : I divided y by x

    8 120 : 120/8 = 15

    9.5 138 : 138/9.5 = 14.53 can be rounded up to 15

    10 147 : 147/10 = 14.70 can be rounded up to 15

    6 88 : 88/6 = 14.67 can be rounded up to 15

    7 108 : 108/7 = 15.42 can be rounded down to 15

    4 62 : 62/4 = 15.50 can be rounded down to 15

    y = 15x

    120.00 = 15.00 8.00

    142.50 = 15.00 9.50

    150.00 = 15.00 10.00

    90.00 = 15.00 6.00

    105.00 = 15.00 7.00

    60.00 = 15.00 4.00
