Re: In the x-y plane there is a line K, (x/a)+(y/b)=1. What is the x-inter [#permalink]
If we need x intercept then y should be equal to 0 in the given equation.

So the given equation becomes X=a.

1. a= b
then X=a = b ( no unique solution )
Not Sufficient
2. a=1
then X=a=1 ( Unique Solution)
Sufficient

So Ans : B Only Statement 2 is sufficient to answer the given question.

==> If you modify the original condition and the question, the x-intercept is the value of x when y=0, hence from (x/a)=1, you get x=a, so you only need to find a.

Therefore, the answer is B.
Answer: B
