U(7, 7)
U'(-3,7)
Explanation:
reflecting upon the value of x=2 that means we reflect over y- axis.
*for reflections the distance from the line of reflection to the object is equal to the distance to the image point.
d = 2 + 2 = 4 units.
7 - 4 = 3(since reflection is done towards the negative side)
x' = -3.
