  1. OBJECTIVES You will be able to define slope. Tell whether it is positive or negative. Be able to measure slope using rise over run. Be able to measure slope with two coordinates. 4.1 Slope On your way up to define slope Mark Moss – Valencia College 2011

  2. down Slope UP

  3. Slope Can you name a few other slopes?

  4. Slope How can we describe slope?

  5. Slope SLOPE IS THE STEEPNESS OF THE LINE

  6. Slope What do we call slopes go up?

  7. Slope POSITIVE.

  8. Slope What do we call slopes that go down?

  9. Slope NEGATIVE

  10. Slope Slope -3 -2 -1 0 1 2 3

  11. Slope Slope So, how do we measure the steepness of slope?

  12. Measuring Slope Slope is measured by the rise over the run. The rise is the change in the y-axis. Distance up and down Slope = m = Distance across The run is the change in the x-axis.

  13. Rise over Run y Slope Calculate Rise x Run

  14. Example 1 = y Slope Calculate x

  15. Example = y Slope Calculate x

  16. You Try = y Slope Calculate x

  17. Example 1 = y Slope Calculate x1, y1 (4,7) (2,1) x x2, y2

  18. Example = y Slope x1, y1 Calculate (-2,7) (4,1) x x2, y2

  19. You Try = y Slope x1, y1 Calculate x2, y2 (-5,6) (3,5) x (-7,0) x2, y2 (7,-1) x1, y1

  20. Review Questions 1 Describe slope in words: What is positive slope? What is negative slope? Calculate the slope between (4,-4) and (-3,2)

  21. Review y Given the graph, calculate the slope. x

  22. OBJECTIVES YOU MASTERED You will be able to define slope. Tell whether it is positive or negative. Be able to measure slope using rise over run. Be able to measure slope with two coordinates. Slope If you reached this point – you are a master Mark Moss – Valencia College 2011
