Question
The matrix 
show the reflection in
- x-axis
- y-axis
- y = x
- y = -x
Hint:
General synopsis of reflection with respect to y-axis.
The correct answer is: y-axis
* 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.
* Matrix representation is the efficient way for the transformation of points.
* Every vertex is placed in columns.
Given That:
The matrix show the reflection in
>>> From the matrix given there is change in the sign of x-coordinate with equal magnitude(a=-a) and y-coordinate remains same(b=b).>>> Therefore, the point (a, b) changes to (-a, b) after reflection.
>>>Hence, the line of reflection becomes y-axis.
* The reflection matrix in the y-axis =
