Quadrilateral abcd is reflected across the x-axis and then reflect across the y-axis to form quadrilateral a? b? c? d? . if the coordinates of vertex a are (-7, 3), what are the coordinates of vertex a? ?

A'(7,-3)

Step-by-step explanation:

We were given the coordinates, A(-7,3) of quadrilateral ABCD and we want to find the image of A after a reflection across the x-axis followed by a reflection in the y-axis.

When we reflect A(-7,3) across the x-axis we negate the y-coordinate to obtain: (-7,-3).

When the image is again reflected in the across the y-axis, we negate the x-coordinate to get (--7,-3).

Therefore the coordinates of A' after the composed transformation is (7,-3).
