Question

Quadrilateral LMNO is reflected over the y-axis. What are the coordinates of the image of the vertex N?

A. (-4, 3)
B. (4, 3)
C. (-4, -3)
D. (4, -3)

Answer 1

B. (4, 3)

Explanation:

Since N is four units to the left of the y-axis, reflecting it would make it four units to the right of the y-axis, so you would base this off of the y-coordinate.

I am joyous to assist you anytime.

Answer 2

B

Explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ), thus

N(- 4, 3 ) → N'(4, 3 ) → B
