The table lists the annual cost (in dollars) of tuition and fees at private four-year colleges for the selected years. Complete parts (a) through (c) below. Year 2000 2002 2004 2006 2008 2013 2010 2012 Tuition and Fees 16,073 18,061 20,046 22,304 24,813 26,766 28,984 30,093 0 13 1 13 Do the data appear to lie roughly along a straight line? OA. No, they appear to lie in a V-shape. OB. No, they appear to lie on a curved line. O C. No, they seem to be scattered randomly. D. Yes, they appear to lie on a straight line. 0 13 0 13 (b) Let t= 0 correspond to the year 2000. Use the points (0,16073) and (13,30093) to determine a linear equation that models the data. What does the slope of the graph of the equation indicate? The linear equation is C = 1078.46t + 16,073. (Use integers or decimals for any numbers in the expression. Round to the nearest hundredth as needed.) The slope of the graph indicates that the annual costs of tuition and fees at the colleges are increasing by about $1600 per year. (Use the answer from the previous part to find this answer. Type an integer or a decimal.)
