Find if it is the parabola, ellipse, circle, or hyperbola. If it is parabola compute vertex point, and find which way it will open (up, down, right, or left). If it is ellipse, determine center point and vertices and find if it is short and wide or tall and thin. If it is circle, determine center and radius. If its hyperbola, compute center point and find which way it will open (and and down, or right and left).
