On a large sheet of graphing paper, joan has drawn a picture of a castle by connecting vertex points on the grid. she decides that the picture would look better if it were reversed, changing the left side for the right side and the right side for the left. the vertex point that marks the top of the castle's flagpole is at (122, 73). if she reflected the picture across the y-axis, then what would be the new coordinates for the top of the flagpole? type your answer as an ordered pair, like this example: (-12, 34).
