Question

1. In the graph below, point D is reflected across the y-axis. What are the coordinates of its

image?
2
(3,-1)
(3, 1)
(-3,-1)
(-3, 1)

Answer 1

3

Explanation:

Answer 2

The coordinates of the image of D after a reflection across the y-axis is C. (-3, -1)

How to determine the coordinates of its image?

From the question, we have the following parameters that can be used in our computation:

D = (3, -1)

Also, we have

A reflection across the y-axis

The rule of this reflection is

(x, y) = (-x, y)

Using the above as a guide, we have the following:

D' = (-3, -1)

Hence. the coordinates of its image is (-3, -1)
