The vertices of a triangle are P(–4, 1), Q(–2, –8), and R(8, –1). Name the vertices of the image reflected across the xaxis.
P'(–4, –1), Q'(–2, 8), R' (8, 1)
P'(4, –1), Q'(2, 8), R'(–8, 1)
P'(4, 1), Q'(2, 8), R'(–8, –1)
P'(–4, 1), Q'(–2, –8), R'(8, –1)
Thank You! :) your help is much appreciated

Steve,
reflecting across the xaxis just reverses the sign of the ycoordinate:
(x,y) > (x,y)
so, P(4,1) > P'(4,1)
that eliminates two of the choices. Can you take it from here?
