Symmetric with respect to the line y = x if (b,a) is on the graph whenever (a,@ is on the graph. TESTS FOR SYMMETRY (Fig. 8-3): 1. If substituting -x for x leads to the same equation, the graph has symmetry with respect to the y-axis. 2. If substituting -y for y leads to the same equation, the graph has symmetry with respect to the x-axis. 3. If simultaneously substituting -x for x and -y for y leads to the same equation, the graph has symmetry with respect to the origin. Note: a graph may have none of these three symmetries, one, or all three.
