  1. 3.3 Slope of a Line Today’s Date: 9/27/11

  2. Slope (change in y) Slope = y y (change in x) x Zero x rise run Undefined

  3. Slope Given 2 points: (slope) Ex 1) Find the slope of the line with points (–2, 3) & (4, –1)

  4. Slope The slope of the line Ax + By = C is: Ex 2) Find the slope of 5x – 2y= 20 A = 5 B = –2 OR Change to slope-intercept form y = mx + b slope

  5. Find the value of k so that the line has slope m Ex 3) 6x + ky = 10, m = –2 A = 6 B = k (k) (k)( )

  6. Find the value of k so that the line has slope m Ex 4) (k, k + 1), (3, 2) , m = 3 (3 – k) (3 – k) don’t forget ( )

  7. Homework #302 Pg. 116 1 – 23 odd & 39 – 45 odd For # 1 – 11: = 0 = Undefined
