The position of the image of an object viewed in a plane mirror is virtual and symmetrically opposite to the position of the object from the mirror.
The image formed by a plane mirror is located behind the mirror, at the same distance as the object is in front of the mirror (assuming the mirror and object are on the same plane). Therefore, the correct statement would be: "The image of an object viewed in a plane mirror is located behind the mirror, at the same distance as the object is in front of the mirror."
