Answer 2

Answer: The correct option is

(A) (-1, 5).

Step-by-step explanation: Given that the point Q(-1, 5) is reflected across the line x = -1.

We are to find the co-ordinates of the image of Q.

For the point Q(-1, 5), we have

x co-ordinate = -1 and y co-ordinate = 5.

So, the point (-1, 5) lies on the line x = -1. The point Q(-1, 5) and the line x = -1 is shown in the attached figure below.

Therefore, the reflection of the point Q(-1, 5) across the line x = - 1 will be itself. Thus, the co-ordinates of the image of Q(-1, 5) after reflection is Q(-1, 5).

Option (A) is CORRECT.
