Answer:
W'(1,-5), X'(6,-3), Y'(1,-1), Z'(-4,-3)
Step-by-step explanation:
Reflection over the x-axis changes the sign of the y-coordinate. The x-coordinate remains unchanged.
The reflected points are ...
W'(1,-5), X'(6,-3), Y'(1,-1), Z'(-4,-3)
We have
so this is indeed a difference of squares. Factorizing would give
making the answer D.
We can further factor the first term here and write
but that's clearly out of the scope of this question.
