Explanation

Answer: A

A reflection is a transformation that acts like a mirror: It swaps all pairs of points that are on exactly opposite sides of the line of reflection.

The line of reflection can be defined by an equation or by two points it passes through.

The line of reflection is also called the mirror line.

Therefore,

the axis of reflection is

\(y-x-6=0\).

Jawapan: A

Pantulan adalah transformasi yang bertindak seperti cermin: Ia menukar semua pasang titik yang berada di sisi yang berlawanan dari garis pantulan.

Garis pantulan dapat ditentukan oleh persamaan atau oleh dua titik yang dilaluinya.

Garis pantulan juga disebut garis cermin.

Oleh itu,

paksi pantulan tersebut ialah

\(y-x-6=0\).
