Question
What is the line of reflection for 
and its image?
- x-axis
- y-axis
- y = x
- y = -x
Hint:
Observe the graph and then obtain the line of reflection.
The correct answer is: y = -x
* In Geometry, a reflection is known as a flip. A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.
*It is a type of transformation that produces mirror image of the shape.
Given That:
>>>From figure:
The coordinates A(0,2);B(0,4);C(3,1);D(3,5) after reflection became A'(-2,0);B'(-4,0);C'(-1,-3);D'(-5,-3).
>>>The point (a, b) became (-b, -a) after reflection.
>>>This can be done by reflecting the point on the line y=-x.
>>>Therefore, the line of reflection is y = -x.
From the graph, the line of reflection is y = -x.
