+1776 Point A is reflected over the line shown below to point B. Find the coordinates of B.
Write your answer as an ordered pair (x,y).
Point A is (5,7), and the line is y = x.
+410 The general formula across line y = x, is (a,b)→(b,a), so the result is (7,5).
But if you want a more general solution that can work for any line, then it is much more difficult, but turning to imaginary numbers + roots of unity is one way to do it.
