Yes
like (x-h)^2= 4(a(y-k) is a parabola
(x-h)^2/a^2 + (y-k)^2/b^2 = 1 is an ellipse
if a^2=b^2 then circle of radius a^2=b^2=r^2
if - sign between, then ellipse turns to hyperbola etc
Explain how you can tell what kind of conic section a quadratic equation describes without graphing the equation.
Can you do this by writing the equation in standard form? (That's what my answer key says... but I don't know how/if it's actually right)
