Sliva [168]

Answer:

The answer is 65

Step-by-step explanation:

Since x corresponds to the number of years since​ 2000, the year 2009 corresponds to an​ x-value of 9.

​Next, find the​ y-value on the trend line that corresponds to an​ x-value of 9. The problem statement has been updated to show lines traced from the​ x-value of 9 to the trend line and then to the​ y-value.

Notice that the point​ (9,70) appears to lie on the trend line.

​Therefore, in​ 2009, approximately 70 million passengers travelled through the airport.

Question is complete.
