Question

A point has

the coordinates (m, 0) and m + 0.
Which reflection of the point will produce an image located at (0, -m)?
• a reflection of the point across the x-axis
O a reflection of the point across the y-axis
O a reflection of the point across the line y = X
a reflection of the point across the line y = -X

Answer 1

A reflection of the point across the line y = -x

Explanation:

General rule for reflection across line y = -x is

(a,b) -------> (-b , -a)
