  • Slide 1
  • Slope Supplement 2 Find a slope Graphing with Slope
  • Slide 2
  • Slope Slope describes the direction of a line.
  • Slide 3
  • Guard against 0 in the denominator Slope If x 1 x 2, the slope of the line through the distinct points (x 1, y 1 ) and (x 2, y 2 ) is Why is this needed ?
  • Slide 4
  • x-axis y-axis Find the slope between (-3, 6) and (5, 2) Rise Run -4 8 2 ==
  • Slide 5
  • Find the slope between (-3, 6) and (5, 2)
  • Slide 6
  • Find the Slope (5, -2) (11, 2) (3, 9) Green Blue Red
  • Slide 7
  • Find the slope between (5, 4) and (5, 2). STOP This slope is undefined.
  • Slide 8
  • x-axis y-axis Find the slope between (5, 4) and (5, 2). Rise Run -2 0 Undefined ==
  • Slide 9
  • Find the slope between (5, 4) and (-3, 4). STOP This slope is zero.
  • Slide 10
  • x-axis y-axis Find the slope between (5, 4) and (-3, 4). Rise Run 0 -8 Zero ==
  • Slide 11
  • From these results we can see... The slope of a vertical line is undefined. The slope of a horizontal line is 0.
  • Slide 12
  • x-axis y-axis Graph the line that goes through (1, -3) with (1,-3)
  • Slide 13
  • Using Slope to Graph Graph the line that contains (4, 5) and has a slope of 3/2. (4, 5) (6, 8) (8, 11)
  • Slide 14
  • Using Slope to Graph Graph (0, 8) (4, 5) (8, 2)
  • Slide 15
  • Slope Worksheet 10 points Find the slope of the lines that contain the following pairs of points. a.(2, 3) and (-4, -5) b.(0, 0) and (2, 3) c.(3, 0) and (7, 4) d.(7, 4) and (3, 0) e.(2, 3) and (2, -5) Sketch a graph of the following lines. 1. y = 4x 8 2. y = -3x + 6 3. 4. 5.
