Apoint has the coordinates (0, k). which reflection of the point will produce an image at the same coordinates, (0, k)?
a. a reflection of the point across the x-axis
b. a reflection of the point across the y-axis
c. a reflection of the point across the line y = x
d. a reflection of the point across the line y = –x

Option: b is the correct answer.

b.)    a reflection of the point across the y-axis.

We know that:

             When a point (x,y) is reflected across :

Here we have a point as : (0,k)

Now after reflection the coordinates of the point remains the same i.e. (0,k)

            This means that the reflection was done across the y-axis.

b. x- 48 =120
