Lessons
  1. Find the slope of a line that is parallel and perpendicular to the following.
    1. y = -23 {2 \over 3} x5-5
    2. 4x - 7y + 4 = 0
    3. 23x14y+52=0{2 \over 3}x - {1 \over 4}y + {5 \over 2} =0
  2. Given the equations of the following line determine if they parallel, perpendicular, or neither.
    1. 3x + 4y = 8
      -9x -12y = 6
    2. x - 3y = 9
      2x + 6y = 3
    3. 2x + 5y = 10
      -5x + 2y = 5
  3. Find the equation of the line that passes through given point and is i.) parallel ii.) perpendicular to the given line.
    1. p (2,4); y = 2x - 6
    2. p (-5,2); 23x+34y=12 {2 \over 3}x + {3 \over 4}y =12
