Rate of Change and Calculations

The video tutorial explains how to determine the rate of change per unit using a table of values. It describes the rate of change as the change in y over the change in x, similar to the concept of slope. The tutorial walks through calculating the changes in y and x values, and then demonstrates how to compute the rate of change by dividing these values. The consistent rate of change is confirmed as 75.

What is the rate of change often compared to in mathematics?

• The area of a circle

• The perimeter of a square

• The volume of a cube

• The slope of a line

In the given example, what is the change in y when moving from 60,075 to 67,575?

• 500

• 7,500

• 1,000

• 10,000

What is the change in x when moving from 800 to 900 in the example?

• 150

• 100

• 200

• 50

How do you calculate the rate of change from the given values?

• Add the change in y and the change in x

• Divide the change in y by the change in x

• Multiply the change in y by the change in x

• Subtract the change in x from the change in y

What is the consistent rate of change found in the example?

• 75

• 25

• 100

• 50
