Reading Line Graph

Front

What is a line graph used for?

Back

A line graph is used to display data points over a period of time, showing trends and changes in values.

Front

How do you identify an increase in sales on a line graph?

Back

An increase in sales is identified by an upward slope in the line connecting the data points.

Front

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

Back

The x-axis typically represents the independent variable, often time.

Front

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

Back

The y-axis typically represents the dependent variable, such as sales or population.

Front

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

Back

The peak value is determined by identifying the highest point on the line graph.

Front

What does a downward slope indicate on a line graph?

Back

A downward slope indicates a decrease in the value of the dependent variable.

Front

How can you find the average value represented in a line graph?

Back

The average value can be found by calculating the mean of the data points represented on the graph.

Front

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

Back

Data points represent specific values at given intervals, allowing for analysis of trends.

Front

How do you read the scale on a line graph?

Back

The scale on a line graph indicates the range of values for the dependent variable, showing increments.

Front

What information can be derived from the intervals on the x-axis?

Back

The intervals on the x-axis indicate the time periods or categories over which the data is measured.
