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

D. (3, -5) on edge

Answer 2

(5, 3)

Explanation:

Since we are reflecting by the x-axis, the x-cooridnate would stay the same.

Vertex D is 3 units dow from the x-axis. By reflecting in using the x=0 reference,the y-coordinate would be a positivo 3 now.
