A line is passing through the point \((4,3)\) and the sum of its intercepts made on the coordinate axes is 14 . Then an equation of that line is

  1. A \(3 x+4 y=24\)
  2. B \(6 x+8 y=24\)
  3. C \(4 x+3 y=25\)
  4. D \(4 x-3 y=7\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(3 x+4 y=24\)

Step-by-step Solution

Detailed explanation

Let intercepts be \(a, b\). \(\frac{x}{a} + \frac{y}{b} = 1\) \(a + b = 14 \implies b = 14 - a\) Line passes through \((4,3)\): \(\frac{4}{a} + \frac{3}{14 - a} = 1\) \(4(14 - a) + 3a = a(14 - a)\) \(56 - 4a + 3a = 14a - a^2\) \(a^2 - 15a + 56 = 0\)…
