Heya......!!!
The sign conventions for a mirror or a lens are set as per the Cartesian sign conventions.
➡All the distances parallel to the principal axis are measured from the pole. The distances below the principle axis and on the left side of the mirror/lens, are negative. Whereas distances above the principle axis and on the right side of the mirror/lens are positive.
➡We know that >>> Magnification = height of image/height of object
OR
➡ Magnification= - ( image distance)/ object distance
➡While calculating this, we have to take the appropriate signs with respect to the object and the image.
HOPE IT HELPS U ☺
