Which best describes the relationship between the two lines below? 

Line p: 6x + 3y =12

Line q: -4x = 2y -2

• Parallel

• Perpendicular

• Same Line

• Intersecting, but not perpendicular

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)
