Answer:
124 million in 2007
Step-by-step explanation:
This is a proportion match question, we consider 121-116 to represent a 9 year change = 5 rate of change per 9 years. We need to find one year so we divide 5/9=0.55 per year growth. =2002- 2007= 0.55 million x 5 = 2.8million growth add 121 million = 121 =123.8 in 2007 = 124 million to nearest m.

Notice the same x values show up repeatedly in the other ordered pairs with different y values. Only one y value for every x value
