Answer:
C. (x, -y)
Explanation:
Given quadrilateral ABCD, we want to determine the coordinate describing the vertex when it is reflected over the x-axis.
When a point (x,y) is reflected across the x-axis, the transformation rule is given below:
[tex](x,y)\to(x,-y)[/tex]
Given that (x,y) describes a coordinate of quadrilateral ABCD, the coordinates of A''B''C''D'' will be:
[tex](x,y)\to(x,-y)[/tex]
The coordinate of the corresponding vertex is (x, -y).
Option C is correct.
