Consider the following population and year graph: find the slope of the line AB and using it find what will be the population in the year 2010.

Explanation

Given points are `A(1985, 92) ` and `B(1995, 97).`

So,Slope of
`AB=(97−92)/(1995−1985)
=5/(10)=1/2`

Let population in year 2010 be x crores.

then `C(2010, x)` lies on the line.


∴ Slope of `BC=(y−97)/(2010−1995)`

`=(y−97)/(15)`
