Answer:
Step-by-step explanation:
When we apply a reflection in a point over an axis this is what happens, especially if we consider, a reflexion of those points over y-axis
A(0,-3) B(-1,0) C(1,1) D(-1,-1)
Since the reflection over y-axis equals to (-x,y) we are going to have a change. But the question says we're not going to have any change at all. Calculating to prove it:
(-x,y) Reflection across y-axis
A(0,-3) then A'(0,-3)
B(-1,0) then =B'(1,0)
C(1,1) then C'(-1,1)
D(-1,-1) then D'(1,-1)
Hence the point is A, whose A' did not change its x-coordinate across the y-axis after reflected.

If you look at the picture, you set it up as part over whole is equal to percent over 100. then you just multiply across.
