Line Graphs

Front

What is a line graph?

Back

A line graph is a type of chart that shows information as a series of data points called 'markers' connected by straight line segments. It is used to display data that changes over time.

Front

What does the slope of a line in a line graph indicate?

Back

The slope of a line in a line graph indicates the rate of change. An upward slope means the values are increasing, while a downward slope means the values are decreasing.

Front

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

Back

The highest value on a line graph is found at the peak point of the line, where the line reaches its highest point.

Front

What does it mean if a line graph is flat?

Back

If a line graph is flat, it means that the values are staying the same over time; there is no increase or decrease.

Front

How can you find the difference between two values on a line graph?

Back

To find the difference between two values on a line graph, locate the two points on the graph and subtract the lower value from the higher value.

Front

What is the purpose of a title on a line graph?

Back

The title of a line graph explains what the graph is about, providing context for the data being presented.

Front

What do the axes on a line graph represent?

Back

The horizontal axis (x-axis) typically represents the independent variable (like time), while the vertical axis (y-axis) represents the dependent variable (like sales or weight).

Front

How do you read data points on a line graph?

Back

To read data points on a line graph, find the point where the line intersects with the vertical and horizontal axes, and note the corresponding values.

Front

What does it mean when a line graph shows a steep slope?

Back

A steep slope on a line graph indicates a rapid increase or decrease in the values over a short period of time.

Front

What is a data point in a line graph?

Back

A data point in a line graph is a specific value represented by a marker on the graph, showing the relationship between the two variables.
