The line Ax+By+6=0Ax + By + 6 = 0 passes through the points (1,2)(1, 2) and (3,−1)(3, -1). Which ordered pair (A,B)(A, B) satisfies this condition? (a) (−127,−187)\left(-\dfrac{12}{7},-\dfrac{18}{7}\right) (b) (−187,−127)\left(-\dfrac{18}{7},-\dfrac{12}{7}\right) (c) (−3,−2)(-3,-2) (d) (187,127)\left(\dfrac{18}{7},\dfrac{12}{7}\right)
