Which equation best represents the line of best fit for this set of data?
(1) y = 15x (3) y = 0.1x - 0.4
(2) y = 0.07x (4) y = 14.1x + 5.8
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
