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 read a line graph?

Back

To read a line graph, look at the x-axis (horizontal) for the time period and the y-axis (vertical) for the values. Follow the line to see how the values change over time.

Front

What does an increase in a line graph indicate?

Back

An increase in a line graph indicates that the values are going up over the time period shown.

Front

What does a decrease in a line graph indicate?

Back

A decrease in a line graph indicates that the values are going down over the time period shown.

Front

What does it mean if a line is horizontal in a line graph?

Back

If a line is horizontal, it means that the values are constant and not changing over the time period shown.

Front

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

Back

To find the difference, locate the two values on the y-axis, subtract the smaller value from the larger value.

Front

What information can you gather from a line graph?

Back

You can gather information about trends, increases or decreases in values, and comparisons between different time periods.

Front

What year had the highest number of students in the provided line graph?

Back

The year with the highest number of students can be determined by looking for the highest point on the line graph.

Front

How do you determine if a value is higher in one year compared to another on a line graph?

Back

Compare the y-axis values for the two years in question; the year with the higher y-axis value has more students.

Front

What is the significance of the x-axis in a line graph?

Back

The x-axis typically represents the time intervals (years, months, etc.) over which the data is collected.
