Consider the given population and year graph. Find the slope of the line AB and using it, find what will be the population in the year 2010?
उत्तर
Since line AB passes through points A (1985, 92) and B (1995, 97), its slope is
Let y be the population in the year 2010. Then, according to the given graph, line AB must pass through point C (2010, y).
∴Slope of AB = Slope of BC
Thus, the slope of line AB is 1/2 , while in the year 2010, the population will be 104.5 crores
