What are the coordinates of the image of vertex F after a reflection across the line y = –x?

the coordinates of the image vertex f after a reflection across the line y=-x (3, -1)Solution: The coordinates of the vertices are a,E = (-1, -5)F = (1, -3)G = (-2, -3)H = (2, -5), While reflecting any point on the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed).I.and any point with co-ordinates (x, y) after reflection about y=-x (-y, -x)therefore, the new coordinates of the vertices,E = (5, 1)F = (3, -1)G = (3, 2)H = (5, -2)therefore, the coordinates of the image of the vertex point f after a reflection across the line y=-x (3, -1)
