The point A divides the join of the points \( (-5,1) \) and \( (3 \), 5) in the ratio \( \mathrm{k}: 1 \) and coordinates of points \( \mathrm{B} \) and \( \mathrm{C} \) are
\( \mathrm{P} \) \( (1,5) \) and \( (7,-2) \) respectively. If the area of \( \triangle A B C \) be 2

W. units, then \( \mathrm{k} \) equals
(2) 6,7
(3) \( 7,31 / 9 \)
(4) \( 9,31 / 9 \)
