Graph the equation x + y2 = 100 on a graphing calculator. Identify the conic section. Then identify the center and intercepts for circles and ellipses, or the vertices and direction that the graph opens for parabolas and hyperbolas ellipse center: (0, 0) intercepts: (10, 0), (0, +10) parabola vertex: (0, 0) opens right circle center: (0, 0) intercepts: (+10, 0), (0, 10) hyperbola vertices: (+10, 0) opens horizontally
