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:
