I know it is probably hard to read these questions so I will put them here. 1. The graph starts in the year 1 C. E. How many years did it take for the population to reach 1 Billion people?

2.It took 124 years to grow from 1 billion to 2 billion. How long did I take to get from 6 billion to 7 billion people? What does this mean about the rate of population growth?

3. Suggest a reason why the population grew so slowly before the 1800's.

If you could help me that would be great. I don't want any links, I want actual answers. Thanks in advance! ​
