Answer:
PLATO
Step-by-step explanation:
The attached diagram may be helpful. In the diagram, each reflected point is connected to the original by a line segment perpendicular to the line of reflection.
<u>Reflection across the x-axis</u>
(3, 1) ⇒ (3, -1)
(x, y) ⇒ (x, -y)
<u>Reflection across the y-axis</u>
(3, 1) ⇒ (-3, 1)
(x, y) ⇒ (-x, y)
<u>Reflection across y = x</u>
(3, 1) ⇒ (1, 3)
(x, y) ⇒ (y, x)
<u>Reflection across y = -x</u>
(3, 1) ⇒ (-1, -3)
(x, y) ⇒ (-y, -x)
