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
