R²通常運算與明示全稱代數證書。操作=subspace-line-membership;資料={"a":4,"b":-4,"x":-9,"y":0}。請依 [point,normal,equation_value,in_line] 欄序回答。
G001 — R²通常運算與明示全稱代數證書。操作=subspace-line-membership;資料={"a":4,"b":-4,"x":-9,"y":0}。請依 [point,normal,equation_value,in_line] 欄序回答。沿用原題明示的論域、假設與來源 MKO 定義。本題已完成第二對話數理與中英語義覆核,並由原始參數逐題獨立重算模型、答案與每個算術步驟;原題仍為 candidate。
