2. Rate of Change Time Walking (seconds) Distance Walked (feet) 14 28 312 This means you walked 4 feet every second.

3. Rate of Change Number of Floor Tiles Area of Tiled Surface (in 2 ) 348 696 9144 +3 +48 in 2 Number of tiles This means 16 in 2 of surface is tiled for each floor tile that is used.

4. Examples Number of Computer Games Total Cost ($) 278 4156 6234 1.2. Time Driving (h) Distance Traveled (mi) 276 4152 6228

5. Linear or Not Linear? If the rate of change is CONSTANT through the entire function, then the function is linear. A positive rate of change indicates an increase over time. A negative rate of change indicates that a quantity is decreasing.
