The point (2, -7) is reflected across the x-axis. What are the coordinates of the image of the point?

  (2, 7)

The rule used here is which applies for any x axis reflection. The x coordinate stays the same while the y coordinate flips from positive to negative, or vice versa.

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i
