we could use the points to 650 and 16. Um, 1050 if we let x equal zero be the year 2000 when we have a year 2002 and for our y cornets Johnson millions. So we have 650 million and from 1.5 billion. Okay, so r b find midpoint with the midpoint is add appear X corns take half and add up your why hornets and take half. So that midpoint would be a 18 halves or nine and 6 50 plus 10 50 Half of that is a 15. So this would be your midpoint for part C. How would that be interpreted in 2009? Um, the number of passengers it was 100 and 50 going.
