From $2003$ onward, the number of daily visitors to a website increased by $200\%$ every two years. So, for example, the number
of visitors in $2011$ was $200\%$ more than the number of visitors in $2009$. In what year was the number of daily visitors $800\%$ more than the number of daily visitors in $2003$? Explain, in words, why your answer is correct.
If the number of visitors was, say, 100 people in 2003, then in 2005 that number would have gone up to 300 people, which is a 200% increase. And that number would have gone up to 900 people in 2007, which is an 800% increase.
The graph forms a straight line going downwards. The straight line means that the speed is constant. It is going downwards meaning it is stopping.
The best statement that represents the graph is:
