Given the equation x²-18x + 2y² + 17 = 0 find the foci, vertices, directrix, axis, and asymptotes, where applicable. Name of the conic section: Foci: (from left to right or top to bottom) Vertices: (from left to right or top to bottom) Directrix: ? Axis ? ? く Asymptotes: (in increasing order of slope) Y x + y = x +
