Answer:
reflect over the x-axis
Step-by-step explanation:
Transformation is the movement of point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.
If a point A(x, y) is rotated 180° clockwise about the origin the new position would be A'(-x, -y)
If a point A(x, y) is reflected over the y-axis the new position would be A'(-x, y).
If a point A(x, y) is reflected over the x-axis the new position would be A'(x, -y)
If a point A(x, y) is translated a units left the new position would be A'(x-a, y).
The rectangle has points at (2, 2), (2, 5), (7,2), (7,5). If the rectangle is reflected over the x-axis the new position would be at (2, -2), (2, -5), (7, -2), (7, -5) which is at the fourth quadrant
