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.

How do you read a line graph?

Back

To read a line graph, look at the x-axis (horizontal) for the independent variable and the y-axis (vertical) for the dependent variable. Find the point where the two intersect to determine the value.

Front

What does the slope of a line on a graph represent?

Back

The slope of a line on a graph represents the rate of change between the two variables. A steep slope indicates a rapid change, while a gentle slope indicates a slow change.

Front

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

Back

A horizontal line on a graph indicates that there is no change in the dependent variable as the independent variable changes.

Front

What is the purpose of a title on a graph?

Back

The title of a graph provides a clear description of what the graph represents, helping the viewer understand the data being presented.

Front

How can you determine the highest value on a line graph?

Back

To determine the highest value on a line graph, look for the highest point on the line, which corresponds to the maximum value of the dependent variable.

Front

What does it mean if a line graph shows a downward trend?

Back

A downward trend on a line graph indicates that the value of the dependent variable is decreasing over time.

Front

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

Back

To find the difference between two values on a line graph, identify the two points on the line, read their corresponding values, and subtract the smaller value from the larger value.

Front

What is the significance of data points on a line graph?

Back

Data points on a line graph represent specific values of the variables being measured. They are plotted to show the relationship between the two variables.

Front

What does it mean if a line graph has multiple lines?

Back

If a line graph has multiple lines, it indicates that there are multiple sets of data being compared, allowing for analysis of relationships between different variables.
