Line Graph Review

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.

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

Back

The x-axis is the horizontal line on a graph that typically represents the independent variable, such as time or categories.

Front

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

Back

The y-axis is the vertical line on a graph that typically represents the dependent variable, such as quantity or measurement.

Front

How do you read a line graph?

Back

To read a line graph, look at the x-axis to find the category or time period, then follow the line up or down to see the corresponding value on the y-axis.

Front

What is the purpose of a line graph?

Back

The purpose of a line graph is to visually represent data to show trends, changes, and relationships over time.

Front

What does an upward slope on a line graph indicate?

Back

An upward slope indicates that the value of the dependent variable is increasing over time.

Front

What does a downward slope on a line graph indicate?

Back

A downward slope indicates that the value of the dependent variable is decreasing over time.

Front

What does a flat line on a line graph indicate?

Back

A flat line indicates that there is no change in the value of the dependent variable over the time period shown.

Front

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

Back

To find the difference, locate the two points on the graph, read their values on the y-axis, and subtract the smaller value from the larger value.

Front

What is a data point in a line graph?

Back

A data point is a specific value plotted on the graph, representing the relationship between the independent and dependent variables.
