Answer 1

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)`
