We have a point O (2; 12). It is necessary to find the abscissa of a point symmetric to point O relative to the ordinate axis.
The coordinates of point O are positive, respectively, the point is located in the first coordinate quarter.
Symmetry is relative to the ordinate, which means that the ordinate of the point does not change, only the abscissa changes to the opposite.
This means that the abscissa of a point symmetric to point O relative to the ordinate axis will be equal to -2.
