The gradients of perpendicular lines have a negative reciprocal gradient.

a) If A = 4, then the gradient of the line perpendicular to A would be -
(1)/(4)

b) If B = -3, then the gradient of the line perpendicular to B would be
(1)/(3)

c) If C =
(2)/(3), then the gradient of the line perpendicular to C would be -
(3)/(2)
