how do I find reflect it? would I have to keep the points the same of would point B replace point A

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 [tex](x,y) \to (x, -y)[/tex], which means (x, y) turns into (x, -y)
So (-2, -2) becomes (-2, 2) after using that rule.
Repeat for points B through D
Check out the diagram below.
