Point A is at (-2, -2). When you reflect it over the x axis, the y coordinate flips from negative to positive. The x coordinate stays the same.
The reflection rule stated algebraically is
, which means (x, y) turns into (x, -y)
So (-2, -2) becomes (-2, 2) after using that rule.
Repeat for points B through D
- B is at (-2, -4) which moves to (-2, 4)
- C is at (-5, -4) which moves to (-5, 4)
- D is at (-5, -2) which moves to (-5, 2)
