Interpret Line Graphs (Level 2)

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

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

Back

The x-axis (horizontal axis) typically represents the independent variable, which is the variable that is controlled or changed in an experiment.

Front

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

Back

The y-axis (vertical axis) usually represents the dependent variable, which is the variable that is measured or observed in an experiment.

Front

How do you determine the highest point on a line graph?

Back

The highest point on a line graph is determined by locating the peak of the line, which indicates the maximum value of the dependent variable.

Front

How do you find the lowest point on a line graph?

Back

The lowest point on a line graph is found by identifying the trough of the line, which shows the minimum value of the dependent variable.

Front

What does a steep slope in a line graph indicate?

Back

A steep slope indicates a rapid change in the value of the dependent variable over a small change in the independent variable.

Front

What does a flat slope in a line graph indicate?

Back

A flat slope indicates that there is little to no change in the value of the dependent variable as the independent variable changes.

Front

How can you identify trends in a line graph?

Back

Trends in a line graph can be identified by observing the overall direction of the line (increasing, decreasing, or constant) over a period of time.

Front

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

Back

Data points represent specific values of the dependent variable at given values of the independent variable, providing a visual representation of the data.

Front

How do you read values from a line graph?

Back

To read values from a line graph, locate the data point on the line and trace vertically to the y-axis for the dependent variable value and horizontally to the x-axis for the independent variable value.
