Understanding Constant Rate of Change

The video tutorial explains how to calculate the constant rate of change for investments over time. It uses two examples: one where the investment value increases and another where it decreases. The process involves writing the information as ordered pairs, calculating the change in investment worth and years, and determining the rate of change using the slope formula. The tutorial emphasizes understanding the positive or negative nature of the rate to determine if the investment is increasing or decreasing.

What was the initial value of the investment in 2003?

• $41,550

• $47,650

• $47,500

• $31,400

How do we determine the constant rate of change?

• By subtracting the change in input from the change in output

• By adding the change in output to the change in input

• By dividing the change in output by the change in input

• By multiplying the change in output by the change in input

Why is it important to organize data as ordered pairs?

• To decrease the investment value

• To increase the investment value

• To confuse the reader

• To make calculations easier

What is the constant rate of change for the investment from 2003 to 2016?

• $1,250 per year

• $950 per year

• $850 per year

• $1,650 per year

What is the significance of the constant rate of change being positive?

• The investment value is fluctuating

• The investment value is increasing

• The investment value is constant

• The investment value is decreasing

In the second example, what was the value of the investment in 2008?

• $31,400

• $47,500

• $41,550

• $47,650

What was the value of the investment in 2015 in the second example?

• $41,550

• $47,650

• $47,500

• $31,400

How is the constant rate of change calculated in the second example?

• By adding the change in years to the change in investment

• By dividing the change in investment by the change in years

• By multiplying the change in investment by the change in years

• By subtracting the change in years from the change in investment

What is the constant rate of change for the investment from 2008 to 2015?

• $1,650 per year

• $1,250 per year

• $850 per year

• $950 per year

What does a negative constant rate of change indicate?

• The investment value is decreasing

• The investment value is increasing

• The investment value is constant

• The investment value is fluctuating
