Reading 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 commonly used to visualize data trends over time.

Front

What does a downward trend in a line graph indicate?

Back

A downward trend in a line graph indicates that the values are decreasing over the specified time period.

Front

How can you determine the value at a specific point on a line graph?

Back

To determine the value at a specific point on a line graph, locate the point on the x-axis (horizontal) and draw a vertical line up to the graph to find the corresponding value on the y-axis (vertical).

Front

What information can you gather from the slope of a line in a line graph?

Back

The slope of a line in a line graph indicates the rate of change between the two variables represented. A steeper slope indicates a greater rate of change.

Front

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

Back

The highest point on a line graph is identified by locating the peak of the line, which represents the maximum value of the data set.

Front

What does it mean if two points on a line graph are at the same height?

Back

If two points on a line graph are at the same height, it means that the values for those two corresponding x-axis points are equal.

Front

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

Back

To find the average value represented in a line graph, sum all the values of the data points and divide by the number of data points.

Front

What is the significance 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., sales, temperature).

Front

How can you interpret a flat line in a line graph?

Back

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

Front

What does the area under the line in a line graph represent?

Back

The area under the line in a line graph can represent the total accumulation of the dependent variable over the time period, depending on the context.
