What is the Constant Rate of Change?

Back

The Constant Rate of Change is the rate at which one quantity changes in relation to another. It is often represented as a slope in a linear relationship.

Front

How do you calculate the rate of change between two points (x1, y1) and (x2, y2)?

Back

Rate of Change = (y2 - y1) / (x2 - x1). This formula gives the slope of the line connecting the two points.

Front

If the water level in a pool decreases from 10 feet to 2 feet over 4 hours, what is the constant rate of change?

Back

Decreases 2 feet per hour.

Front

What does a negative rate of change indicate?

Back

A negative rate of change indicates that the quantity is decreasing over time.

Front

What does a positive rate of change indicate?

Back

A positive rate of change indicates that the quantity is increasing over time.

Front

What is an additive relationship?

Back

An additive relationship is when a quantity increases or decreases by a constant amount.

Front

What is a multiplicative relationship?

Back

A multiplicative relationship is when a quantity increases or decreases by a constant factor.

Front

If a car travels at a constant speed of 60 miles per hour, what is the rate of change of distance with respect to time?

Back

The rate of change is 60 miles per hour.

Front

How do you interpret a slope of -5 in a graph?

Back

A slope of -5 means that for every 1 unit increase in x, y decreases by 5 units.

Front

What is the formula for finding the slope of a line?

Back

Slope (m) = (y2 - y1) / (x2 - x1).
