Write an equation in slope intercept form that is perpendicular to y = -3x + 4 and passes through the point (9,5).

• y = 3x - 32

• y = -3x + 22

• y = 1/3x - 8

• y = 1/3x + 2

Write an equation in standard form that is perpendicular to y = 1/4x + 2 and passes through the origin.

• y = -4x - 0

• 4x + y = 0

• y = 4x - 2

• x - 4y = 0
