Line Graph

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 (horizontal axis) 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 (vertical axis) typically represents the dependent variable, such as measurements or quantities.

Front

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

Back

The highest point on a line graph is determined by identifying the maximum value on the Y-axis corresponding to the data points.

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 line in a line graph indicate?

Back

A flat line indicates that there is no change in the value of the dependent variable over the range of the independent variable.

Front

How can you find the average value from a line graph?

Back

To find the average value, you can sum the values of the dependent variable at various points and divide by the number of points.

Front

What is the purpose of labeling axes in a line graph?

Back

Labeling axes helps to clarify what each axis represents, making it easier for viewers to understand the data being presented.

Front

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

Back

Multiple lines on a line graph can represent different data sets, allowing for comparison between them.

Front

How can you identify trends in a line graph?

Back

Trends can be identified by observing the direction of the lines (increasing, decreasing, or constant) over time.
