Reading Graphs

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 show trends over time.

Front

How do you determine the distance traveled from a distance-time graph?

Back

The distance traveled can be determined by looking at the vertical axis (distance) at a specific time on the horizontal axis (time). The value on the vertical axis indicates how far the object has traveled.

Front

What does a horizontal line on a distance-time graph represent?

Back

A horizontal line indicates that the object is at rest, meaning it is not changing its position over time.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope indicates that the object is moving quickly, as it covers a large distance in a short amount of time.

Front

What does a downward slope on a distance-time graph represent?

Back

A downward slope indicates that the object is returning to its starting position.

Front

How can you find the speed of an object from a distance-time graph?

Back

Speed can be calculated by finding the slope of the line on the graph. The formula is speed = distance/time.

Front

What is the significance of the x-axis and y-axis in a distance-time graph?

Back

The x-axis typically represents time, while the y-axis represents distance. This allows for the visualization of how distance changes over time.

Front

What does it mean when two lines on a graph intersect?

Back

When two lines intersect on a graph, it indicates that the two objects being represented have the same position at that specific time.

Front

What is the purpose of a key in a graph?

Back

A key explains the symbols or colors used in the graph, helping the reader understand what each line or bar represents.

Front

How can you tell if an object is moving faster than another on a graph?

Back

You can tell if an object is moving faster by comparing the slopes of their lines; the steeper the slope, the faster the object is moving.
