Given,
The coordinates of the given figure are J(1, 3), U(0, 5), R(1, 5), C(3, 2)
Here, the reflection about only y axis,
The coordinates of the x-axis remain the same,
This finds the distance from the point to y = 2 by subtracting the point's y-coordinate from 2, then moves the point that far to the other side of y = 2 by adding 2.
The reflected coordinates are,
