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 used to visualize trends over time.

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

Back

The slope of a line on a graph is determined by the formula (change in y) / (change in x). It represents the rate of change between the two variables.

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

Back

The x-axis typically represents the independent variable, which is the variable that is manipulated or changed in an experiment.

Front

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

Back

The y-axis typically represents the dependent variable, which is the variable that is measured or observed in response to changes in the independent variable.

How can you identify trends in a line graph?

Back

Trends in a line graph can be identified by observing the direction of the line: upward indicates an increase, downward indicates a decrease, and horizontal indicates stability.

Front

What does it mean if a line graph has a steep slope?

Back

A steep slope on a line graph indicates a rapid change in the value of the dependent variable with respect to the independent variable.

How do you read values from a line graph?

Back

To read values from a line graph, locate the point on the line corresponding to the desired x-value, then read the y-value at that point.

Front

What is the significance of the points on a line graph?

Back

The points on a line graph represent specific data values at given intervals, showing how the dependent variable changes in relation to the independent variable.

Front

How can you compare two different line graphs?

Back

To compare two different line graphs, look at the slopes, trends, and values at specific points to analyze how the two sets of data relate to each other.

What does it indicate if two lines on a graph intersect?

Back

If two lines on a graph intersect, it indicates that the two variables have the same value at that point, which may represent a significant relationship or change.
