Answer:
(x, y) ⟶ (−x, −y); A′ is at (5, −1)
Step-by-step explanation:
When you rotate a point 180° about the origin, it travels along the circumference of a circle and ends up in a diagonally opposite location.
The x and y values of its coordinates become the negatives of the original values.
The rule is
(x,y) ⟶ (-x,-y)
If the coordinates of A are (-5,1),
The coordinates of A' are (5,-1).
The figure below shows the graph or your rectangle and its rotated image.
