Qualitative graphs

Front

What is a qualitative graph?

Back

A qualitative graph is a type of graph that represents the relationship between variables without using numerical values, focusing instead on the general trends and behaviors of the data.

What does an increasing interval on a graph indicate?

Back

An increasing interval on a graph indicates that the value of the dependent variable is rising as the independent variable increases.

Front

What does a decreasing interval on a graph indicate?

Back

A decreasing interval on a graph indicates that the value of the dependent variable is falling as the independent variable increases.

Front

What is a linear relationship in a graph?

Back

A linear relationship in a graph is represented by a straight line, indicating a constant rate of change between the variables.

Front

What is a nonlinear relationship in a graph?

Back

A nonlinear relationship in a graph is represented by a curve, indicating that the rate of change between the variables is not constant.

Front

How can you identify a section where an object is at rest on a graph?

Back

A section where an object is at rest on a graph is identified by a horizontal line, indicating that the dependent variable does not change as the independent variable increases.

Front

What does the slope of a graph represent?

Back

The slope of a graph represents the rate of change of the dependent variable with respect to the independent variable.

Front

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

Back

The y-intercept is the point where the graph crosses the y-axis, representing the value of the dependent variable when the independent variable is zero.

Front

How do you determine the total distance traveled from a graph?

Back

The total distance traveled can be determined by calculating the area under the graph or by summing the lengths of the intervals represented.

Front

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

Back

A flat section on a speed-time graph indicates that the object is moving at a constant speed.
