Find the coordinates of the images of the following points under reflection in the y-axis : (i) (2, -5) (ii) (iii) (0, -7).

(i) We know that, Rule to find reflection of a point in y-axis : 1. Change the sign of abscissa i.e. x-coordinate. 2. Retain the ordinate i.e. y-coordinate. ∴ Point P'(-2, -5) is the image on reflection. Hence, (-2, -5) is the image of the point (2, -5) on reflection in y-axis. (ii) We know that, Rule to find reflection of a point in y-axis : 1. Change the sign of abscissa i.e. x-coordinate. 2. Retain the ordinate i.e. y-coordinate. ∴ Point P' is the image on reflection. Hence, is the image of the point on reflection in y-axis. (iii) We know that, Rule to find reflection of a point in y-axis : 1. Change the sign of abscissa i.e. x-coordinate. 2. Retain the ordinate i.e. y-coordinate. ∴ Point P'(0, -7) is the image on reflection. Hence, (0, -7) is the image of the point (0, -7) on reflection in y-axis.
