a) Draw a line graph for the data.
Plot the points on a coordinate system.
Run a Linear Regression against the points in your data:
(0,34),(10,38),(20,43),(30,47),etc.
Population = 0.4143x + 34.1429
b) Use the line graph to predict the population in the year 2010.
Population(2010) = 0.4142*60 + 34.1429 = 59 (million)
