5.) The vertices of a triangle are P(4, 1), Q(2, -8), and R(-8, 1). What are the vertices of the image reflected across the y-axis?

a.) P'(4, -1), Q'(2, 8), and R'(-8, -1)
b.) P'(-4, 1), Q'(-2, -8), and R'(8, 1)
c.) P'(-4, -1), Q'(-2, 8), and R'(8, -1)
d.) P'(4, 1), Q'(2, -8), and R'(-8, 1)

Respuesta :

Answer:

(b)

Step-by-step explanation:

Under a reflection in the y-axis

a point (x, y ) → (- x, y ), hence

P(4, 1 ) → P'(- 4, 1 )

Q(2, - 8 ) → Q'(- 2, - 8 )

R(- 8, 1 ) → R'(8, 1 )
