Hi,
x-2y+n =0
From(1) : line pass through (8,0).So, 8+n=0
Sufficient
From(2) : line pass through (0,-4). 8+n=0
Sufficient
Hence, D

IMO D
a)x-intercept means value of x when y=0. Thus 2 variables are known. we can find n
Sufficient
b)y-intercept means value of y when x=0. Thus 2 variables are known. we can find n
