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

• y = 3x - 2

• y = -1/3x - 5

• y = 3x - 4

Use the equations given to determine if the following lines are parallel, perpendicular, neither or both.
y=4x-2
y-3=-1/4(x-8)

• parallel

• perpendicular

• neither parallel nor perpendicular

• both parallel and perpendicular
