Question

Write the coordinates of the vertices after a reflection over the x-axis. 1072

Answer 1

The reflection about x-axis results in same x coodinate with oppositive of y coordinate. It can be expressed as,

$(x,y)\rightarrow(x,-y)$

Determine the coordinates of the vertices after reflection over the x-axis.

$Q(6,-8)\rightarrow Q^{\prime}(6,8)$$R(7,-8)\rightarrow R^{\prime}(7,8)$$S(7,-5)\rightarrow Q^{\prime}(7,5)$$T(6,-5)\rightarrow T^{\prime}(6,5)$
