Question 121428
Y=mX+b
USING THE POINTS (5,18)(10,42) WE HAVE A SLOPE OF:
(42-18)/(10-5)=24/5=4.8.
NOW USING ONE SET OF POINTS WE FIND THE Y INERCEPT.
18=4.8*5+b
b=18-24
b=-6
NOW WE HAVE THE LINE EQUATION:
Y=4.8X-6
WHEN X=11 THE Y=4.8*11-6 OR Y=46.8 
this says that the population in 2010 will be 46.8 thousand.
