Answer:
<u><em></em></u>
<u><em>The final answer, or D.</em></u>
Step-by-step explanation:
When flipping a shape over the y axis, <u>the y coordinates stay the same</u>, while the <u>x coordinates are opposite.</u> <em>(If the x coordinates are negative, the flipped shape will have positive x coordinates.)</em>
The shape that fits this description is<u> D. or the answer at the very bottom.</u>

Answer:
- (8, -8)
- 100 square units
Step-by-step explanation:
The diagonals of a rectangle have the same midpoint, so for points A, B, C, D, we must have ...
(A+C)/2 = (B+D)/2
D = A + C - B
D = (-2, -8) +(8, 2) -(-2, 2) = (-2+8+2, -8+2-2)
D = (8, -8)
__
The side lengths are 2-(-8) = 10, and 8-(-2) = 10. The area is the product of the side lengths, so is 10×10 = 100 square units.

<em>Comment on side lengths</em>
When the end points of one side are on the same vertical line, the length of that side is the difference of y-coordinates. When the points lie on the same horizontal line, the side length is the difference of x-coordinates.
