1. SLOPE LESS 5-1

2. MATH VOCABULARY Slope: The diagonal “slope” of a line on a graph that runs through given points

3. UNDERSTANDING SLOPE Slope = m m = rise = up/down run right

4. SLOPE OF A LINE POSITIVE SLOPE NEGATIVE SLOPE

5. SLOPE OF A LINE UNDEFINED SLOPENO SLOPE = 0

6. COUNTING UNITS TO FIND SLOPE When we count units… we count the rise between two clearly identified points run

7. COUNTING UNITS TO FIND SLOPE M =

8. USING COORDINATES TO FIND SLOPE Another way to find slope… by slope formula m = y² - y¹ x² - x¹

9. USING COORDINATES TO FIND SLOPE (2, 1) and (5, 7) m = y² - y¹ x² - x¹ Label & Plug in: m = 7 – 1 5 – 2 (4, 0) and (-1, 5) m = y² - y¹ x² - x¹ Label & Plug in: m = 5 – 0 -1 – 4

10. PRACTICE… Find the slope of the given points: a)(1, 2) and (4, 2) b)(5, 8) and (-3, -4) c)(5, -2) and (5, 8)
