P'(–4, –1), Q'(–2, 8), and R'(8, 1)
P' (–4, –1), Q' (–2, 8), and R' (8, 1)
P'(4, –1), Q'(2, 8), and R'(–8, 1)
P' (4, –1), Q' (2, 8), and R' (–8, 1)
P'(4, 1), Q'(2, –8), and R'(–8, –1)
P' (4, 1), Q' (2, –8), and R' (–8, –1)
P'(–4, 1), Q'(–2, –8), and R'(8, –1)
The correct answer is P'(–4, –1), Q'(–2, 8), and R'(8, 1).
To find the vertices of the image reflected across the x-axis, we need to change the sign of the y-coordinates of each vertex.
The original vertices are P(-4, 1), Q(-2, -8), and R(8, -1).
Changing the sign of the y-coordinate for each vertex, we get:
P'(-4, -1), Q'(-2, 8), and R'(8, 1).
Therefore, the correct answer is:
P' (-4, -1), Q' (-2, 8), and R' (8, 1).
