Question

On a coordinate plane, a triangle has points F (3, 4), D (5, negative 3), and E (1, negative 2).

What are the coordinates of the image of vertex D after a reflection across the x-axis?

(5, 3)
(–5, –3)
(–3, 5)
(3, –5)

Answer 1

(5,3)

Explanation:

got it right on edg

Answer 2

(5, 3 )

Explanation:

under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

D (5, - 3 ) → (5, - (- 3) ) → (5, 3 )
