Reading Line Graph Practice

Front

What is a line graph?

Back

A line graph is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. It is used to show trends over time.

Front

How do you determine if a line graph shows an increase or decrease?

Back

You can determine if a line graph shows an increase or decrease by looking at the slope of the line. If the line goes up from left to right, it indicates an increase; if it goes down, it indicates a decrease.

Front

What does it mean if a line graph is constant?

Back

If a line graph is constant, it means that the value does not change over the period shown. The line will be horizontal.

Front

How can you find the difference in values between two points on a line graph?

Back

To find the difference in values between two points on a line graph, subtract the value of the earlier point from the value of the later point.

Front

What information can you gather from the highest point on a line graph?

Back

The highest point on a line graph indicates the maximum value reached during the time period represented.

Front

What does the x-axis typically represent in a line graph?

Back

The x-axis typically represents the independent variable, often time, showing the progression of data points.

Front

What does the y-axis typically represent in a line graph?

Back

The y-axis typically represents the dependent variable, showing the values that correspond to the data points plotted.

Front

How can you tell which year had the most students in a line graph?

Back

You can tell which year had the most students by identifying the highest point on the line graph and checking the corresponding year on the x-axis.

Front

What does a steep slope in a line graph indicate?

Back

A steep slope in a line graph indicates a rapid increase or decrease in the values being represented.

Front

What is the purpose of using a line graph?

Back

The purpose of using a line graph is to visually represent data over time, making it easier to identify trends, patterns, and changes.
