Good method, but E Maths students do not learn the property that the product of the gradients of two perpendicular lines is equal to -1. This property is only learnt in A Maths.

Sadly it is hard to say whether there are other approaches available for this question or not, and I am unable to tell whether the question comes from an E Maths textbook or an A Maths textbook.
