Question 10694: A Fixed-Second-Coordinate Slice on Listed Inputs Only

Original question and givens

Use the declared real polynomial R²→R with coefficients=[6, 1, 1, 1, -1, -1] in the fixed order [1,x,y,x²,x*y,y²]. Keep the two coordinate roles distinct. These explicit slices establish no global continuity, differentiability or vector-valued-function claim. fixed y=1, x input list=[-1, 0, 1] normalized to sorted distinct integers. Give (coefficients,fixed y,normalized inputs,every [x,f(x,y)] row). Empty input lists are allowed.
