Question

What is the reflection of the point (5, -2) in the line x = -1?

A) (-7 , -2) B) (5 , 0) C) (7 , -2) D) (5 , 2)

Answer 1

Answer:

given : P (5, -2)

to find coordinates of P under reflection on x = -1

P (x, y ) => P' => reflection under x= -1

=> P' (- 2- a, b)

=> P' = (-2-5 , - 2)

=> P' ° ( -7 , -2 ) option A
