1. Read the graph carefully. Read all around the graph, including the title and the key.

2. Some questions may try to trick you by leaving out numbers. If all the numbers are not given, it is a very good

idea to fill in all the missing numbers on the graph. To do this, you will need to know the value of each

increment.

3. Sometimes, instead of reading bars or lines, you can compare differences by using a piece of your test book￾let to measure from one point to another or from the end of one bar to the end of another.

Line Graphs

3. In what year is the increase in student popula￾tion projected to be less than the increase in

number of new homes built?

a. 1998

b. 1999

c. 2000

d. 2001

e. 2002

Answer

The answer is c. A look at the graph shows that during

the year 2000 there was a sharper increase in the num￾ber of new homes built than in student population.

The line slopes up steeper there for houses than it does

for student population. Percent of increase is a differ￾ent question and might yield a different answer. Check

Ratios, Proportions, and Percents (p. 109) on percents

for details.
