  1. Introduction To Slope

  2. Slope is a measure of Steepness.

  3. Types of Slope Zero Negative Positive Undefined or No Slope

  4. Slope is sometimes referred to as the “rate of change” between 2 points.

  5. The letter “m” is used to represent slope.

  6. If given 2 points on a line, you may find the slope using the formula

  7. The formula may sometimes be written as What is ∆ ?

  8. Find the slope of the line through the points (3,7) and (5, 19). x1 y1 x2 y2 m = 19 – 7 5 – 3 m = 12 2 m = 6

  9. Intuitive: Find the slope of the line through the points (3,7) and (5, 19). m = 12 m = 6 2

  10. (3, 4) and (-6, -2) x1 y1 x2 y2 m = -2 – 4 -6 – 3 m = -6 -9 m = ⅔

  11. Intuitive: Find the slope of the line through the points (3,4) and (-6, -2). m = -6 m = ⅔ -9

  12. What if the numerator is 0? Then the slope is zero – horizontal line

  13. What if the denominator is 0? Then the slope is undefined – vertical line

  14. If given the graph of a line, find the slope by using the “triangle” method to find the rise over run.

  15. rise = 4 m= rise run run = 5 m= 4/5

  16. Practice: (-2, 8) and (6, 24) (-3, 9) and (-6, -3) (-1, 2) and (-4, -6)

  17. Now let’s use this to graph ...
