Use the image to answer the question.

An illustration shows a coordinate plane with four quadrants. The x-axis ranges from negative 9 to 9 in one unit increments. The y-axis ranges from negative 11 to 11 in one unit increments. Four points are plotted. A square is graphed using the four plotted points as vertices. Point A is plotted at coordinates left parenthesis 3 comma negative 4 right parenthesis. Point B is plotted at coordinates left parenthesis 7 comma negative 4 right parenthesis. Point C is plotted at coordinates left parenthesis 7 comma negative 8 right parenthesis. Point D is plotted at coordinates left parenthesis 3 comma negative 8 right parenthesis. Points A, B, C, and D are connected by solid lines to form square A B C D.

Answer 1

To find the vertices of square A′B′C′D′ after reflecting square ABCD first across the x-axis and then across the y-axis, we can follow these steps:

1. Original Vertices:

   • A(3, -4)
   • B(7, -4)
   • C(7, -8)
   • D(3, -8)

2. Reflecting across the x-axis:

   • The rule for reflection across the x-axis is (x, y) becomes (x, -y).
   • Therefore, the points after the first reflection are:
     • A'(3, 4)
     • B'(7, 4)
     • C'(7, 8)
     • D'(3, 8)

3. Reflecting across the y-axis:

   • The rule for reflection across the y-axis is (x, y) becomes (-x, y).
   • Therefore, the points after the second reflection are:
     • A′(−3, 4)
     • B′(−7, 4)
     • C′(−7, 8)
     • D′(−3, 8)

Thus, the vertices of square A′B′C′D′ are:

• A′(−3, 4)
• B′(−7, 4)
• C′(−7, 8)
• D′(−3, 8)

Therefore, the correct response is: Square A′B′C′D′ has vertices A′(−3, 4), B′(−7, 4), C′(−7, 8), and D′(−3, 8).
