Given that Jogging
is one of the few sports that has been consistently increasing over the
past few years and that the number of people jogging​ (in millions) from the
years 2000 to 2009 is given by the equation y=x+26​,
where x is the number of years after 2000.
Part A
Use this equation or a graph of it to complete the ordered pair (8, ).
Given the equation: y = x + 26, when x = 8, then y = 8 + 26 = 34
Therefore, the complete ordered pair is (8, 34)
Part B
Write a sentence explaining the meaning of the answer to part a.
Given that x is the number of years after 2000, this means that x = 8 refers to 2008.
Therefore, the sentence describing the meaning of the answer to part a is 'The number of people jugging in the year 2008 equals 34 million.'
Part C
If this trend continues, how many joggers will there be in 2017?
For year 2017, x = 17 and the number of joggers in million is given by y = 17 + 26 = 43
Therefore, the number of joggers in 2017 is 43 million.
