Line Graphs

A line graph is a type of graph that shows how something changes over time by connecting points with a line.

Line graphs are best for showing continuous data, such as changes in temperature or population over time.

The x-axis typically represents the time or categories being measured.

The y-axis represents the values or quantities being measured.

To read a line graph, look at the points plotted on the graph and follow the lines to see how values change.

A flat line means that the value is constant and does not change over the time period shown.

An upward slope indicates that the value is increasing over time.

A downward slope indicates that the value is decreasing over time.

To find the total, you may need to add the values at specific points on the graph.

A data point is a specific value plotted on the graph, representing a measurement at a certain time.
