Which transformation of Figure A results in Figure A'?a reflection across the y-axisa reflection across the x-axisa clockwise rotation of 90° about the origina translation 12 units right and 2 units down.

From the figure the coordinates of A are: 
(-8,-4), (-6,-3), (-4,-5)
The coordinates of A' are: (-4,-6),(6,-5),(8,-7)
subtracting 2 corresponding points we get:
[(4--8),(-6--4)]
=(12,-2)
this means that the image has been translated 12 units to the right and 2 units down.
Answer:

a translation 12 units right and 2 units down.
