Question

The coordinates of a quadrilateral are (5,8), (7, 10). (9.12), and (11, 14). After a transformation, the sign of the x-

coordinate for each ordered pair has changed. Which type of transformation occurred?
-))
PLSSSS HELP

Answer 1

Reflection about y axis

Explanation:

A reflection about the y axis will change the sign of the x coordinates

Answer 2

Horizontal translation or a reflection around a vertical axis

Explanation:

If the change in the x-coordinate has been the addition or subtraction of a constant number (same number for all vertices of the quadrilateral), the transformation was a horizontal translation.

If the change in x coordinate was such of from x to its opposite, then the transformation was that of a reflection around the y axis.
