Reflections over the y-axis require the x coordinated to be negated. 3) (x, y)  The rule for a reflection over the y-axis is (x, y) → (x, -y). Reflection across the y-axis changes the sign of the x - coordinate only, that is, (x, y) becomes (-x, y). Since the reflection line is perfectly horizontal, a line  When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed).
