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.

Simple...

when they ask for the rate of change they ask for slope -->>

Using $\frac{ y_{1} - y_{2} }{ x_{1} - x_{2} }$ to find the rate of change for (-3,0) and (-2,-5)

$\frac{0--5}{-3--2}$

$\frac{0+5}{-3+2}$

$\frac{5}{-1}$

m=-5

Thus, your answer.
