1. 5-1B Rate of Change Warm-up (IN) Learning Objective: to understand that slope is the rate of change of one quantity relative to another and to be able to describe the slopes of vertical and horizontal lines. 1. Find the slope of each line.

2. Notes Read p. 308 and Explore p. 309 Slope of a line – rise run EX 1 – Find the slope of the line passing through the points: a. (-3, 0) and (-1, 6) 6-0 -1-(-3) = 6 2 = 3

3. b. (-1, -3) and (5, -3) -3-(-3) 5-(-1) = 6 = 0 0 c. (-2, 1) and (1, -3) -3-1 1-(-2) = 3 -4 d. (0, -1) and (0, 4) 4-(-1) 0-0 = 0 = undefined 5

4. Types of Slopes positive negative zero undefined

5. HW – pg. 313-315 #1-13,16 Out – how is the rate of change related to slope? Summary – so, the big idea is… POW!!
