3.1 Constant Rate of Change

Front

What is a constant rate of change?

Back

A constant rate of change refers to a situation where the change in one quantity is consistent with the change in another quantity over a specific interval. It is often represented as a linear relationship.

How can you identify a constant rate of change from a graph?

Back

A constant rate of change can be identified from a graph by observing a straight line, indicating that the relationship between the two variables is linear.

What is the formula for calculating the rate of change?

Back

The formula for calculating the rate of change is (change in y) / (change in x), often expressed as (y2 - y1) / (x2 - x1).

How do you determine the constant of proportionality from a table of values?

Back

To determine the constant of proportionality from a table of values, divide the value of one quantity by the corresponding value of the other quantity for any pair of values.

What is an example of a real-world scenario that demonstrates a constant rate of change?

Back

An example of a real-world scenario that demonstrates a constant rate of change is the cost of a taxi ride, where the fare increases at a constant rate per mile.

What is the relationship between constant rate of change and linear equations?

Back

The relationship is that a constant rate of change indicates a linear equation, which can be expressed in the form y = mx + b, where m is the slope.

How can you verify if a table of values represents a constant rate of change?

Back

You can verify if a table of values represents a constant rate of change by checking if the differences between consecutive y-values divided by the differences between consecutive x-values are constant.

What does a rate of change of 0 indicate?

Back

A rate of change of 0 indicates that there is no change in the dependent variable as the independent variable changes, resulting in a horizontal line on a graph.
