Polygon ABCDE is reflected to produce polygon ABCDE. What is the equation for the line of reflection?
ОА У-0
OB. X=0
OC x=2
OD. y=1

Answer 1

B. x = 0

Explanation:

we notice that a point and it’s image have the same y-coordinate and opposite x-coordinates

Example :

A(-2 , 2) is a point and A(2 , 2) it’s image by the reflection

`y_(A)=2=y_(A^(\prime ))`

`x_(A)=-2=-x_(A^(\prime ))`

Then the reflection is across the y-axis

Or The equation of the y-axis is x = 0
