For the second question your correct I didn't read it all it says average rate of change for century continues. So you just compute slope using points (1905,1006) and (2005,1129) to compute slope for avg change over century. Then do slope which is average change per year and multiple by number of years from 2005 to 2009 to find estimated population in 2009.
