The green graph shows the number of recreational vehicles sold in the United States, in thousands, for the years 2009€“2014. The red dashed line can be used to approximate the number of recreational vehicles, in thousands, sold in the United States. If we let 0 represent 2009, 1 represent 2010, and so on, then 2014 would be represented by 5. Use the ordered pairs (0, 184.942) and (5, 354.29) to represent 2009 and 2014, respectively.

(a)  Determine the slope of the red dashed line.

(b)  Determine the equation of the red dashed line, using (0, 184.94) as the y-intercept.

(c)  Using the equation you determined in part (b), estimate the number of recreational vehicles sold in the United States in 2012. 

(d) Assuming the trend continues, use the equation you determined in part (b) to determine the year in which 533 thousand recreational vehicles will be sold in the United States.
