Question

The image of a point P(x, y) when reflected in the Y axis is ___

• A. (-x, y)
• B. (x, -y)
• C. (x, 0)
• D. (-x, 0)

Answer 1

The correct option is A

(-x, y)

When reflected through Y axis, the coordinate's x value becomes negative. For an example, if we have, the coordinates (10, 5) its reflection through Y axis gives us (-10, 5) as a resultant point.
