New coordinates of triangle will be $(2,5)$ , $(6,-1)$ and $(4,-3)$

When a point $(x,y)$ is reflected across the $x$ -axis, its coordinates become $(x,-y)$ and hence

the vertices of the triangle, which are $(2,-5)$ , $(6,1)$ and $(4,3)$ , new coordinates of triangle will be $(2,5)$ , $(6,-1)$ and $(4,-3)$ .
