Question

What are the resultant coordinates of (x, y) when it is reflected through the origin?

• A. (-x, y)
• B. (x, -y)
• C. (-x, -y)
• D. (0, -y)

Answer 1

The correct option is C

(-x, -y)

When reflected through the origin, both the coordinates will change their sign i.e. (x, y) becomes (-x, -y) or (-x, -y) becomes (x, y) depending upon the sign. For an example, if we have, the coordinates (-2, 6) its reflection through the origin gives us (2, -6) as a resultant point.
