. A line is drawn through the point
(1, 2) to meet the coordinate axes at P and Q such that it forms a triangle OPQ, where O is the origin, if the area of the triangle OPQ is least, then the slope of the line PQ is?
A: - 14
B: - 4
C: - 2
D: - 12
Let m be the slope of the line PQ then the equation of PQ is y-2=m(x-1)
