Test for symmetry \n     In the equation, leave x alone and replace y with -y.  If you get the same equation, it is symmetric to the x-axis.\nSymmetry to the y-axis \n     (-x, y) is on the graph when (x, y) is. Test for symmetry. \n       In the equation, replace x with -x.  If the equation is the same, it is symmetric to tye y-axis.\nSymmetry to the line y = x. \n     (y, x) is on the graph when (x, y) is. Test for symmetry. \n     Interchange x and y.  If the equation is the same then it is symmetric to the line y = x.\nSymmetry to the origin. \n     (-x, -y) is on the graph when (x, y) is. Test for symmetry. \n     Replace x with -x and y with -y.  If the equation is the same, then it is symmetric to the origin.]
