Warm Up The graph below represents Kim’s distance from home one day as she rode her bike to meet friends and to do a couple of errands for her mom before returning home. 1. Use the graph to describe Kim’s journey. 2. What do the horizontal lines on the graph represent?

Walking, Falling, & Making Money Essential Questions: What is the purpose of using the rate of change to analyze real-world data? For what types of real-world data can you find the rate of change? Why might you find the rate of change? Standard: Calculate and interpret the average rate of change of a function over a specified interval. Estimate the rate of change from a graph. http://youtube/UMx1XVNPPXw

VOCABULARY Speed – distance traveled per unit of time Constant Speed – speed is not increasing or decreasing, but remains the same over time. Average Speed – distance traveled in a given amount of time, which may vary from one point to another.

VOCABULARY Rate of Change – compares two different quantities that are changing. Average Rate of Change – the change in the out value of a quantity divided by the change of input value. Constant Rate of Change – a rate change that stays the same
