To find the missing coordinate, we evaluate the given function at x=5:
[tex]\begin{gathered} y=5+10,^{} \\ y=15. \end{gathered}[/tex]Therefore in 2005, there will be 15 million people jogging.
If the trend continues, to compute how many joggers will there be in 2015, we evaluate the given function at x=2015-2000=15:
[tex]\begin{gathered} y=15+10, \\ y=25. \end{gathered}[/tex]Therefore, in 2015 there will be 25 million joggers.
Answer:
The ordered pair is (5,15), which means that in 2005, there will be 15 million people jogging.
If this continues, in 2015 there will be 25 million joggers.
