Can someone explain this problem and show the work that comes with it

The answer should be A

When the coordinates are reflected across the x-axis, there would be a change on the y-coordinates,while the x-coordinates remains unchanged.

For example: (x,y) would change into (x,-y).

In this case: (-4,6) would change into (-4,-6).

Thus the answer is c.(-4,-6)

Hope it helps!

50 % is the answer !
