Line Graph Practice

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 Y-axis represent in a line graph?

Back

The Y-axis represents the vertical line on a graph, which typically shows the values or measurements of the data being represented.

Front

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

Back

The X-axis represents the horizontal line on a graph, which usually shows the categories or time intervals for the data.

Front

What is the origin in a graph?

Back

The origin is the point where the X-axis and Y-axis intersect, represented by the ordered pair (0,0).

Front

How do you read a point on a line graph?

Back

A point on a line graph is read as an ordered pair (x,y), where 'x' is the value on the X-axis and 'y' is the value on the Y-axis.

Front

What does it mean if a line on a graph is going up?

Back

If a line on a graph is going up, it means that the values are increasing over time.

Front

What does it mean if a line on a graph is going down?

Back

If a line on a graph is going down, it means that the values are decreasing over time.

Front

What is a coordinate?

Back

A coordinate is a set of values that show an exact position on a graph, usually written as (x,y).

Front

What is the purpose of a line graph?

Back

The purpose of a line graph is to visually represent data to show trends, changes, and relationships over time.

Front

What is the greatest increase in a line graph?

Back

The greatest increase in a line graph is the largest upward change between two points.
