Algebra Graphs

Conic Sections (see also Conic Sections)	Point x^2 + y^2 = 0	Circle x^2 + y^2 = r^2
Ellipse x^2 / a^2 + y^2 / b^2 = 1	Ellipse x^2 / b^2 + y^2 / a^2 = 1	Hyperbola x^2 / a^2 - y^2 / b^2 = 1
Parabola 4px = y^2	Parabola 4py = x^2	Hyperbola y^2 / a^2 - x^2 / b^2 = 1
For any of the above with a center at (j, k) instead of (0,0), replace each x term with (x-j) and each y term with (y-k) to get the desired equation.
