Analyzing Graphs

Front

What is a graph?

Back

A visual representation of data that shows the relationship between different variables.

Front

What does a steady pace on a graph look like?

Back

A straight horizontal line indicating constant speed over time.

Front

What does a downward slope on a graph indicate?

Back

A decrease in the value of the variable being measured, such as descending a mountain.

Front

What does an upward slope on a graph indicate?

Back

An increase in the value of the variable being measured, such as climbing a mountain.

Front

What does a vertical line on a graph represent?

Back

An undefined or infinite speed, often indicating a sudden stop or change in direction.

Front

How can you determine the total time spent in an activity from a graph?

Back

By measuring the length of the time interval on the x-axis that corresponds to the activity.

Front

What does a flat line on a graph represent?

Back

A period of no change in the variable, indicating that the subject is stationary.

Front

What is the significance of the x-axis in a graph?

Back

It typically represents the independent variable, often time.

Front

What is the significance of the y-axis in a graph?

Back

It typically represents the dependent variable, such as distance or speed.

Front

How can you identify a change in speed on a graph?

Back

By observing the slope of the line; a steeper slope indicates a faster speed.
