Back

The y-axis is the vertical line on a graph that usually represents the dependent variable or the quantity being measured.

How do you find the highest point on a line graph?

Back

The highest point on a line graph is found by looking for the peak or the highest marker on the line.

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 value of the dependent variable is increasing.

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 value of the dependent variable is decreasing.

Front

How can you tell how much something increased or decreased on a line graph?

Back

You can tell how much something increased or decreased by looking at the difference in values between two points on the line.

Front

What is the purpose of labels on a line graph?

Back

Labels on a line graph help to identify what the axes represent and provide context for the data.

Front

What is a data point in a line graph?

Back

A data point is a specific value plotted on the graph that represents a measurement at a certain time or condition.

Front

How do you read a line graph?
