Web22 Jan 2016 · To reflect over a vertical line, such as x = a, first translate so the line is shifted to the y-axis, then reflect over it, then translate back so the line is shifted to its original position. ( x, y) ↦ ( x − a, y) ↦ ( a − x, y) ↦ ( 2 a − x, y) In this case to reflex over x = − 1 we shift x ↦ x + 1, reflect ↦ − 1 − x and shift back ↦ − 2 − x
