We will discuss here about some of the examples on reflection in the x-axis or y-axis.
1. The point P whose coordinates are (9, 11) is mapped onto P’ when reflected in the x-axis and then P’ is mapped onto P” when reflected in the y-axis. Find the coordinates of P”.
Solution:
Here P’ has the coordinates (9, -11).
When P’ is mapped onto P” by reflection in the y-axis, the coordinates of P” become (-9, -11).
2. A point P is mapped onto P’ when reflected in the y-axis and P’ is mapped onto P” when reflected in the x-axis. If the coordinates of P” are (-7, 4), find the coordinates of P.
Solution:
Let the coordinates of P be (x, y). Then the coordinates of P’ are (-x, y). So, the coordinates of P” are (-x, -y).
According to the question, the coordinates of P” are (-7, 4). So, -x = -7 and –y = 4.
Therefore, x = 7 and y = -4.
Hence, the coordinates of P are (7, -4).
