By the image we can see that our geometric figure ABCD has the translation:
[tex](x+6,\text{ y-1)}[/tex]after the figure is translated, it is reflected by the X-axis, wich means that the Y coordenate is negative, so our transformation is giving by:
[tex](x+6,\text{ -(y-1)), wich implies, (x+6, -y +1)}[/tex]
