Manatee population. In January 2005, 3143 manateeswere counted in an aerial survey of Florida. In January2011, 4834 manatees were counted. (Source: Florida Fishand Wildlife Conservation Commission.)a) Using the year as the x-coordinate and thenumber of manatees as the y-coordinate, find anequation of the line that contains the two datapoints.b) Use the equation in part (a) to estimate the number ofmanatees counted in January 2010.c) The actual number counted in January 2010 was5067. Does the equation found in part (a) give anaccurate representation of the number of manateescounted each year? Why or why not?
