Mathematically, reflection across the x-axis means a point (x,y) undergoes a change to the y point, (x,-y).

 

Examples:

 

Point α is (4,6), find the relfection across the x-axis of Point α... 

The reflection of Point α across the x-axis is (4,-6)

 

Point γ is (-420, -1337), find the reflection across the x-axis of Point γ... 

The reflection of Point γ across the x-axis is (-420, 1337)
