Determine if the given equations are parallel, perpendicular, or neither.

• Parallel

  y = 1/2x - 2 (m = 1/2)

  y = 1/2x - 1 (m = 1/2)

• Perpendicular

  y = 1/2x -2 (m = 1/2)

  y = -2x - 1 (m = -2)

• Parallel

  y = 2x - 2 (m = 2)

  y = 2x - 1 (m = 2)

• Perpendicular

  y = 2x - 2 (m = 2)

  y = -1/2x - 1 (m = -1/2)

• Neither

  y = -2x + 8 (m = -2)

  y = 3x + 6 (m = 3)

Determine if the given equations are parallel, perpendicular, or neither.

• Parallel

  y = 4/3 x + 5 (m = 4/3)

  y = 4/3x + 1 (m = 4/3)

• Perpendicular

  y = 4/3x + 5 (m = 4/3)

  y = -3/4x + 1 (m = -3/4)

• Parallel

  y = -3/4x + 5 (m = -3/4%

  y = -3/4x + 1 (m = -3/4)

• Perpendicular

  y = -4/3x + 5 (m = -4/3)

  y = 3/4x + 1 (m = 3/4)

• Neither

  y = 4X + 15 (m = 4)

  y = 9x + 12 (m = 9)
