C&CM: Line Graphs: Checkpoint Questions

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 trends over time.

Front

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

Back

The y-axis represents the dependent variable in a line graph, which is the variable being measured or observed.

Front

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

Back

The x-axis represents the independent variable in a line graph, which is the variable that is manipulated or changed.

Front

How do you determine the slope of a line in a graph?

Back

The slope of a line is determined by the rise over run, which is the change in the y-values divided by the change in the x-values between two points on the line.

Front

What is the purpose of labeling axes in a graph?

Back

Labeling axes in a graph provides context and clarity, allowing viewers to understand what variables are being represented and the units of measurement.

Front

What does it mean if a line graph is increasing?

Back

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

Front

What does it mean if a line graph is decreasing?

Back

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

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 in a line graph can be identified by observing the overall direction of the line, whether it is increasing, decreasing, or remaining constant over time.

Front

What is the significance of the title in a line graph?

Back

The title of a line graph summarizes the main topic or purpose of the graph, providing viewers with immediate context.
