Reflection in the x-axis. A reflection in the x-axis can be seen in the picture below in which A is reflected to its image A'. The general rule for a reflection in the x-axis: (A,B) (A, âB) Reflection in the y-axis. A reflection in the y-axis can be seen in the picture below in which A is reflected to its image A'.
PQSR is reflected over the Y-axis making the coordinates of P 1 Q 1 S 1 R 1 : (8,-3); (2,-3); (2,-6); (8,-6). Note how the y-coordinates remain the same but the x-coordinates change to their opposite integer (i.e. the sign changes). This is always the case with reflections over the Y-axis.
