Math Problem Statement
Consider a triangle ∆ whose two sides lie on the x-axis and the line 𝑥 + 𝑦 + 1 = 0. If the orthocenter of ∆ is (1, 1), then the equation of the circle passing through the vertices of the triangle ∆ is (A) 𝑥 2 + 𝑦 2 − 3𝑥 + 𝑦 = 0 (B) 𝑥 2 + 𝑦 2 + 𝑥 + 3𝑦 = 0 (C) 𝑥 2 + 𝑦 2 + 2𝑦 − 1 = 0 (D) 𝑥 2 + 𝑦 2 + 𝑥 + 𝑦 = 0
