4.3 Line Graphs

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 changed or controlled 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 in an experiment.

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 move up or down to find 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 is a data point in a line graph?

Back

A data point is a specific value plotted on the graph, representing the intersection of the x and y values.

Front

How can you identify trends in a line graph?

Back

Trends can be identified by observing the direction of the line: if it goes up, the trend is increasing; if it goes down, the trend is decreasing.

Front

What does it mean if a line graph is flat?

Back

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

Front

What is the significance of the highest point on a line graph?

Back

The highest point on a line graph represents the maximum value of the dependent variable during the time period shown.

Front

What is the significance of the lowest point on a line graph?

Back

The lowest point on a line graph indicates the minimum value of the dependent variable during the time period shown.
