AHSME 1951 Problem 33

The roots of the equation $x^{2}-2x = 0$ can be obtained graphically by finding the abscissas of the points of intersection of each of the following pairs of equations except the pair: $\textbf{(A)}\ y = x^{2}, y = 2x \textbf{(B)}\ y = x^{2}-2x, y = 0 \textbf{(C)}\ y = x, y = x-2 \textbf{(D)}\ y = x^{2}-2x+1, y = 1$ $\textbf{(E)}\ y = x^{2}-1, y = 2x-1$ [Note: Abscissas means x-coordinate.]
