Qualitative graphs

Front

What is a qualitative graph?

Back

A qualitative graph represents relationships between variables without numerical values, focusing on the shape and direction of the graph to convey information.

Front

What does a decreasing section in a graph indicate?

Back

A decreasing section in a graph indicates that the value of the dependent variable is reducing as the independent variable increases.

Front

What does it mean if a graph is linear?

Back

A linear graph shows a constant rate of change, represented by a straight line.

Front

What does it mean if a graph is nonlinear?

Back

A nonlinear graph shows a variable rate of change, represented by a curve or a line that is not straight.

Front

How can you identify an increasing interval on a graph?

Back

An increasing interval is identified when the graph moves upward from left to right, indicating that the dependent variable is increasing.

Front

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

Back

The x-axis typically represents time in a distance-time graph, showing how distance changes over a specific period.

Front

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

Back

The y-axis typically represents distance in a distance-time graph, showing how far an object has traveled.

Front

What does it mean if a graph has multiple decreasing intervals?

Back

Multiple decreasing intervals indicate that there are several periods during which the dependent variable is decreasing.

Front

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

Back

The total time taken can be determined by looking at the x-axis and finding the total duration from the start to the end of the graph.

Front

What does a flat section on a distance-time graph indicate?

Back

A flat section indicates that the object is stationary, meaning there is no change in distance over time.
