#### Explanation:

If by slope you mean gradient, then first work out the gradient of the line that goes through those points:

The perpendicular gradient will be the negative reciprocal (meaning when multiplied together it produces

Normal of

Therefore, gradient is

If you want the equation of one of those lines then:
