The ordered pairs below give the winning times (in seconds) of a 100-meter freestyle swim race at a regularly-held competition from 1984 through 2012. (1984, 54.22)      (2000, 52.13) (1988, 53.23)   (2004, 52.14) (1992, 52.94)   (2008, 51.42) (1996, 52.80)   (2012, 51.30) (a) Sketch a scatter plot of the data. Let y represent the winning time (in seconds) and let  t = 84 represent 1984.   (b) Sketch the line that you think best approximates the data and find an equation of the line. (Round the slope and y-intercept to one decimal place.) y =          (c) Use the regression feature of a graphing utility to find the equation of the least squares regression line that fits the data. (Round the slope and y-intercept to two decimal places.) y =
