The point (2, –4) is reflected across the line y = –1. what are the coordinates of the image?

ANSWER

The coordinates of the image are (2,2)

EXPLANATION

The mapping for a reflection across the line y=k is :

We want to find the image of the point (2,-4) after a reflection in the line y=-1.

In this case k=-1.

This simplifies to,

Hence the image is (2,2)
