The reflection about x-axis results in same x coodinate with oppositive of y coordinate. It can be expressed as,
[tex](x,y)\rightarrow(x,-y)[/tex]
Determine the coordinates of the vertices after reflection over the x-axis.
[tex]Q(6,-8)\rightarrow Q^{\prime}(6,8)[/tex][tex]R(7,-8)\rightarrow R^{\prime}(7,8)[/tex][tex]S(7,-5)\rightarrow Q^{\prime}(7,5)[/tex][tex]T(6,-5)\rightarrow T^{\prime}(6,5)[/tex]
