2. Finding The Slope of a Line

3. Slopes are commonly associated with mountains.

4. The slope we are studying is associated with the graph of a line.

5. Definitions of Slope Measures steepness Ratio of rise over run The change in y over the change in x

6. Steepness

7. Vertical Change Horizontal Change This ratio is also known as Rise Run

8. Given a graph 1.Find 2 points 2.Count Rise (y) and Run (x) 3.Rise and reduce (check direction + -) Run

9. Find Slope

10. Find the slope of the following line.

11. The slope is… 1 2

12. Find the slope of the line.

13. The slope is…. -3

14. Given an equation 1.Solve for y 2.Coefficient of x = m

15. y = 2x + 8

16. Given 2 points 1.Stack points 2.Change in y (rise) 3. Change in x (run) 4. Rise/run and reduce

17. (3, 8) and (2, 6)

18. Given a table 1.Find change in y (rise) 2.Find change in x (run) 3. Rise/ Run and reduce

19. x14710 y8642
