Can you answer questions about line graphs?
A line graph is a graph that organizes and compares how data changes over time.

What is this line graph recording?
The number of feet above sea level that the water is at certain times of the day
Let's look at some new data Madelyn found about her sister and answer questions about what its line graph should look like.
What is this table recording?
![Data Chart: Marissa's Height Records. Age in years. Inches, 10 48 inches, 11 49 incehs, 12 52 inches, 13 56 inches, 14 62 inches, 15 65 inches.](https://s3.amazonaws.com/content.accelerate-ed.com/Elementary/docs/Math3_AE/images/28.4_pg5_2.png)
- the height of a person
- the height of a building
- the weight of a child
Correct! The height of a person is what the table is recording.
Look at the labels at the top of the data table.

Correct! The graph matches the data table given.
Remember that the horizontal axis, or bottom, must have units of time.

Remember that the horizontal axis, or bottom, must have units of time.
Which of the following is NOT likely to happen to the line graph if we plot Marissa’s height at age 16?
- The line will go up.
- The line will go down.
- The line will stay at the same number of inches.
The line will not go down. Marissa will either grow or stay the same, but she will not get shorter.
Correct! The line will go down.
