  1. Slopes Mrs. Bowker Click to see more. What is Slope?

  2. Slopes (or steepness) of lines are seen everywhere.

  3. The steepness of the roof of a house is referred to as the pitch of the roof by home builders.

  4. Malibu House

  5. Ranch House

  6. Ski Cabin

  7. Give one reason why some homes have roofs which have a greater pitch. There is less snow build up in the wintertime.

  8. Engineers refer to the slope of a road as the grade.

  9. They often refer to the slope as a percentage.

  10. Slopes and Lines run rise The slope of a line is the steepnessof the line.

  11. Slopes and Lines fall crawl

  12. Slope = Fall Crawl =

  13. 8 100 A grade of 8% would mean that for every run of 100 units, there is a rise of 8 units.

  14. The steepness of wheelchair ramps is of great importance to handicapped persons. 1 12 The slope of wheelchair ramps is usually about If the rise is 1.5 m, what is the run? Ans: 18 m

  15. Determine the slope of the line segment. 9 cm 5 cm We use the letter m because in French the word for “to go up” is monter. René Descartes(1596-1650) was from France and he was the first to define the Cartesian Plane.

  16. 3 m Determine the slope (pitch) of the roof. 5 m Because the slope is a ratio, there are no units such as cm or cm2.

  17. SLOPE

  18. Determine the slope of the staircase. 2 3 3 3

  19. Determine the slope of the line segment. y 7 4 x

  20. Determine the slope of the line segment. y –5 7 x

  21. Determine the slope of the line segment. y 6 Horizontal lines have a slope of zero. x

  22. = any number Is always ahorizontalline. horizontal line What does an upside-down h look like? y Zero slope

  23. Determine the slope of the line segment. y 5 Vertical lines have slopes which are undefined. x

  24. = any number Is always averticalline. Vertical line What does an upside-down and right-side up V look like? Undefined slope

  25. negative positive undefined zero

  26. Determine the slope of the line segment y 5 40 = 8 x

  27. Determine the slope of the line segment y –2 60 x

  28. Draw a line which has a slope of Draw a line which has a slope of 2

  29. Draw a line which has a slope of –5 6 –5 6

  30. Draw a line which has a slope of … b) 3 a) – 3 1 –3 3 1 1 –3 3 1
