According to industry sources, online banking is expected to take off in the near future. The projected number of households (in millions) using this service is given in the following table: 
(Here, x = 0 corresponds to the beginning of 1998.) Find an equation of the least-squares line for these data. Please round the coefficients in your equation to three decimal places. Use the result to estimate the number of households using online banking at the beginning of 2007, assuming the projection is accurate.
A) y = 2.709x + 4.662; 29.043 million
B) y = 2.709x + 4.662; 28.813 million
C) y = 12.3x + 21.06; 131.390 million
D) y = 12.3x + 21.06; 131.760 million
