The equation of a line is x - 2y = 2. What is the equation of the line that passes through the point (3, -4) and is perpendicular to this line?

• y = 2x - 4

• y = ½ x - 1

• y - 4 = -2(x + 3)

  
  

• y + 4 = -2(x - 3)

• y + 4 = ½ (x - 3)

Two lines are perpendicular. The equation of the first line is 4x - y = -1. Which of the following cannot be the equation of the perpendicular line?

• x + 4y = 2

• 8y = -2 x - 16
