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
(x,y) \to (x, -y), 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)

Check out the diagram below.

Count from each point to the x-axis across and go back out the same number on the opposite side of the x-axis

For instance from point d to the x axis is 2 so now start on the xaxis at -5,0 and go up 2 more so the new point for point D would be -5,2
