A straight line through the point A(3, 4) is such that its intercept between the axes is bisected at A. Its equation is
  1. x + y = 7
  2. 3x − 4y + 7 = 0
  3. 4x + 3y = 24
  4. 3x + 4y = 25

Solution

The equation of axes is $x y=0$ $\Rightarrow$ the equation of the line is $\frac{x \cdot 4+y \cdot 3}{2}=12 \Rightarrow 4 x+3 y=24$
