AABC has vertices A(-4, 4), B(-1,2), and C(-4,1). What are the coordinates of
B' after a translation of (x,y)--(x+2, y+1), then a reflection across the x-axis?

Respuesta :

Answer:

(1, - 3 )

Step-by-step explanation:

Using the translation rule (x, y ) → (x + 2, y + 1 ), then

B(- 1, 2 ) → (- 1 + 2, 2 + 1) → (1, 3 )

Under a reflection in the x- axis

a point (x, y ) → (x, - y ), thus

(1, 3 ) → (1, - 3 )
