Each Valid Pair Gives One Solution For $ (x, Y) $. For Each Pair, $ X = \fraca + B2 $, $ Y = \fracb - A2 $, And We Compute All Combinations. Each Pair Contributes 4 Points (positive And Negative $ X, Y $), Except $ (10, 10) $, Which Gives $ X = 10, Y = 0 $, And Its Negative Counterpart $ (-10, 0) $, Contributing Only 2 Distinct Points. - WatchImages World
