Lesson 10 Qualitative Graphs Review

Front

What does a negative slope indicate in a graph?

Back

A negative slope indicates that as one variable increases, the other variable decreases.

Front

What does a positive slope indicate in a graph?

Back

A positive slope indicates that as one variable increases, the other variable also increases.

Front

What does a zero slope indicate in a graph?

Back

A zero slope indicates that there is no change in the value of the dependent variable as the independent variable changes.

Front

What is meant by 'rate of change' in a graph?

Back

Rate of change refers to how much one quantity changes in relation to another quantity.

Front

What does it mean if the rate of change is not constant?

Back

It means that the slope of the graph is changing, indicating that the relationship between the variables is varying.

Front

What is a linear graph?

Back

A linear graph is a graph that represents a constant rate of change, resulting in a straight line.

Front

What is a nonlinear graph?

Back

A nonlinear graph is a graph that does not have a constant rate of change, resulting in 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 rises as you move from left to right.

Front

How can you identify a decreasing interval on a graph?

Back

A decreasing interval is identified when the graph falls as you move from left to right.

Front

What does it mean if a section of a graph is flat?

Back

A flat section of a graph indicates that the value of the dependent variable is constant over that interval.
