If the algebraic sum of the perpendicular distances from the point (3, – InterviewSolution

1.	If the algebraic sum of the perpendicular distances from the point (3,1),(-1,2) and (1,3) to a variable line is zero, and \|{:(x^2+1,x+1,x+2),(2x+3,3x+2,x+4),(x+4,4x+3,2x+5):}\|=mx^4+nx3+px^2+qx+r, then the variable line always passes through the point
