Calculating the Constant Rate of Change

The video tutorial explains how to calculate the rate of change of a linear function using four representations: verbal, algebraic, numeric, and graphical. It begins with an example of a pool being emptied and highlights common mistakes in calculating slope. The tutorial then explores each representation in detail, providing examples and practice problems to reinforce understanding.

What is the symbolic representation of the gallons remaining in the pool after t hours?

Describe the numeric representation of the rate of change using a table of values.

What points would you choose to verify the graphical representation of the rate of change?
