Question

If point S is reflected across the y-axis, what are the coordinates of its reflection image.

A. (2,-3)
B.(-2,3)
C.(3,-2)
D.(-3,2)

Answer 1

D) coordinates of its reflection image is ( -3 , 2) .

Explanation:

Given : S ( 3 ,2) If point S is reflected across the y-axis,

To find : what are the coordinates of its reflection image.

Solution : We have given S ( 3 ,2).

By the reflection rule over y -axis : (x ,y) →→ ( -x , y) .

Then x = 3 , y = 2

Then coordinates of its reflection image is

(3 , 2 ) →→ ( -3 , 2) .

Therefore, D) coordinates of its reflection image is ( -3 , 2) .
