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 1997.)

Year, x	0	1	2	3	4	5
Households, y	4.5	7.5	10.0	13.0	15.6	18.0

(a) Find an equation of the least-squares line for these data. (Give numbers to three decimal places.)
y(x) =

(b) Use your result of part (a) to estimate the number of households using online banking at the beginning of 2007, assuming the projection is accurate.
