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)`
