The point (2, –4) is reflected across the line y = –1. what are the coordinates of the image? a. (–5, –4) b. (–4, 2) c. (2, 2) d. (2, 4)

Refer to the diagram shown below.

The x-coordinate does not change during the reflection across y = -1.
The vertical distances of P and P' from y = -1 should be equal to 3.
Therefore
(y - (-1)) = -1 - (-4)
y + 1 = 3
y = 2
The coordinates of P' are (2,2).

(2,2)
