a)The ordered pairs are $$(2005,36.3), (2006,38.5), (2007,41.2), (2008,43.4).$$ b) This ordered pair means that in the year of $2007$ pet-related expenditures were $41.2$ billion dollars. c) The graph of the ordered pairs is on the figure. d) It shows the increase in pet-related expenditures as the years pass.
a) We will write ordered pairs using the year as the 1st coordinate and pet related expenditure as the 2nd coordinate : $$(2005,36.3), (2006,38.5), (2007,41.2), (2008,43.4).$$ b) This ordered pair means that in the year of $2007$ pet-related expenditures were $41.2$ billion dollars. c) The graph of the ordered pairs is on the figure. d) It shows the increase in pet-related expenditures as the years pass.
