Final answer:
The completed ordered pair is (9, 26.6), which represents a projection that the revenue from online advertising in the year 2009 is $26.6 billion.
Step-by-step explanation:
The student's question involves using a linear equation to model the revenue from online advertising. The linear equation given is y = 3.3x - 3.1, where y represents the revenue in billions of dollars and x is the number of years after 2000. To complete the ordered pair (9, ), we substitute x = 9 into the equation, giving us y = 3.3(9) - 3.1, which simplifies to y = 29.7 - 3.1 equals 26.6. The ordered pair is (9, 26.6), meaning that the projected revenue for online advertising in 2009 (9 years after 2000) is $26.6 billion.
