Question

Point P is reflected across two lines. Point A is its reflection image. Which two lines is point P reflected across?

x = 3 and y = 2

x = -2 and y = 2

x = 3 and y = -3

x = -2 and y = -3

Answer 1

the correct answer would be x=3 and y=2

Answer 2

Answer: The two lines are x = -2 and y = 2.

Step-by-step explanation: Given that the point P on the co-ordinate plane is reflected across two lines and A is its image after the reflection.

We are to find the two lines across which the point P is reflected.

The co-ordinates of point P are (0, 0) and the co-ordinates of its image A after reflection from two lines are (-4, 4).

From the given figure, we can note that

the first line of reflection is y = 2. Point C(0, 4) is the image after reflection from first line.

The second line of reflection is x = -2. Point A(-4,4) is the final image after second reflection.

Thus, the two lines are x = -2 and y = 2.
