The vertices of a triangle are p(–8, 6), q(1, –3), and r(–6, –3). name the vertices of
ry-3(δpqr) see below also for layout.

The refrection of a point or set of points across the line y = x will result in a point or set of points whose coordinates are the interchange of the x-value and the y-value of the original point or set of points.

Given that the vertices of a triangle are P(-8, 6), Q(1, -3) and R(-6, -3), the vertices of the triangle formed by the refrection Ry=x(ΔPQR) are P'(6, -8), Q'(-3, 1) and R'(-3, -6).
