1970 29
1980 32
1990 38
2000 42
(a) Draw a line graph for the data.
(b) Use the line graph to predict the population in the year 2010
--------------
Plot the points (80,32) (90.38) (100,42)
Draw a line thru them.
Notice that the y-value increases 6 for each
x-value increase of 10.
Predict the y-value over the x-value of 110.
It should be 48.
