triangle ABC has the vertices A, (-6,2) B (-9,1), C (1,-6). What would be the vertices of ABC' after a reflection across the x-axis

Respuesta :

Answer:

see explanation

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y) → (x, - y), hence

A(- 6, 2) → A'(- 6, - 2)

B(- 9, 1) → B'(- 9, - 1)

C(1, - 6) → C'(1, 6)
