WBJEE · Maths · Straight Lines
The equation of the straight line passing through the point \((4,3)\) and making intercepts on the co-ordinate axes whose sum is \(-1\) is
- A \(\frac{x}{2}-\frac{y}{3}=1\)
- B \(\frac{x}{-2}+\frac{y}{1}=1\)
- C \(-\frac{x}{3}+\frac{y}{2}=1\)
- D \(\frac{x}{1}-\frac{y}{2}=1\)
Answer & Solution
Correct Answer
(B) \(\frac{x}{-2}+\frac{y}{1}=1\)
Step-by-step Solution
Detailed explanation
Hint: Let line be \(\frac{x}{a}+\frac{y}{b}=1\), then \(a+b=-1\) \(\frac{4}{a}-\frac{3}{1+a}=1 \Rightarrow a=\pm 2\)
