Solve the problem.The table lists the average annual cost (in dollars) of tuition and fees at a certain 2-year college for selected years, where year 1 represents 1992, year 3 represents 1994, and so on. Use the ordered pairs (3, 1149) and (9, 1302) to find the equation of a line that approximates the data. (If necessary, round the slope to the nearest hundredth and the y-intercept to the nearest whole number.) 
A. y = 25.5x + 996 B. y = 25.5x + 1073 C. y = 25.5x - 1226 D. y = 51x + 996
