Feb 16, 2020 at 8:57 comment added user130022 Thank you very much for the reply. Could you please give a sketch of the proof or at least a reference? If no three points lie in a line, then i hope they are in general position in plane.
Feb 16, 2020 at 8:21 comment added Sasha Sorry, I misunderstood the question. Indeed, if you take 5 and 4 points in general position on the planes they impose independent conditions on quadrics.
Feb 15, 2020 at 19:20 comment added user130022 Thanks for the answer. But if $Q= H_1\cap H_2$ is the only quadric , then it imposes 9 independent conditions. Thus it does not give any contradiction.

Feb 15, 2020 at 18:31 comment added Sasha No, because the points lie on the quadric $Q = H_1 \cap H_2$.
