#### At the beginning I had to choose our topics. I chose to check the population in India. I chose the years 1961-2015.

#### The first step was to search for information and make a table in Desmos . After I had to make a graph with the information.

this calculate gave me the lines of each time

the graph without the orange line.

### the data

the black line and the table

the green line and the table

the blue line and the table

#### The second step and the most fun step-I had to calculate what is the slope of each line and what is the y-intercept of each line.

the calculation of the blue line

the calculation of the black line

the calculation of the green line.

#### then I had to calculate what will be the population in 2067 and in 2112. I made a line (the orange line) and then I knew what will be the population. I think the population in India will stop in 3,710 years because the population will be more then 4 Billion people and I think India won't be big enough to have more then 4 billion people.

this orange line can tell me what will be the population in Indian in the future.

### Thank you
