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

1 answer

The x-axis is the line y = 0. To reflect a point across the x-axis, we keep the x-coordinate the same and negate the y-coordinate.

The image of point P(-4,1) reflected across the x-axis is P'(-4, -1).
The image of point Q(-2, -8) reflected across the x-axis is Q(-2, 8).
The image of point R(8, -1) reflected across the x-axis is R(8, 1).

Therefore, the vertices of the image reflected across the x-axis are P'(-4, -1), Q(-2, 8), and R(8, 1).
