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. Follow the lines to see how the values change.

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 flat slope indicates little or no change.

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

Back

A horizontal line on a graph indicates that the dependent variable does not change as the independent variable changes. This means the value remains constant.

Front

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

Back

An increasing line on a graph indicates that as the independent variable increases, the dependent variable also increases.

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

Back

A decreasing line on a graph indicates that as the independent variable increases, the dependent variable decreases.

What is the importance of the x-axis and y-axis in a line graph?

Back

The x-axis typically represents the independent variable (e.g., time), while the y-axis represents the dependent variable (e.g., quantity). They help in understanding the relationship between the two variables.

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

Back

The highest point on a line graph is where the line reaches its maximum value on the y-axis. This indicates the greatest amount of the dependent variable.

What does it mean if two lines on a graph intersect?

Back

If two lines on a graph intersect, it indicates that the two variables have the same value at that point. It can show a relationship or comparison between the two data sets.

What is a data point in a line graph?

Back

A data point in a line graph is a specific value that represents the relationship between the independent and dependent variables at a given moment.
