In the year 2011, the average annual cost to employees for employer family health coverage was approximately \$3500. In 2016, that amount was approximately \$4500.
(a) Write a linear equation expressing the average annual cost to employees y in terms of the number of years x after 2000.
(b) What was the average annual cost in 2014?
(c) If the trend continues, what will be the first full year in which costs exceed \$7000?
(a) The linear equation is $y = \boxed{}x + \boxed{}$ (Type an integer or decimal rounded to one decimal place as needed)
(b) The average annual cost in 2014 is $\boxed{}
(c) The first full year in which costs exceed \$7000 is the year $\boxed{}$
