# Find the equation of the line through (1,2) so that the segment of line intercepted between the axes is bisected at this point?

$\begin{array}{1 1}(a)\;y+2x=5\\(b)\;y+2x=4\\(c)\;y+3x=7\\(d)\;y+2x=9\end{array}$

(1,2) is the mid point of $(0,b)$ & $(a,0)$
Hence $\large\frac{a+0}{2}$$=1 a=2 \large\frac{b+0}{2}$$=2$
$b=4$
Hence equation of line is
$(y-4)=\large\frac{0-4}{2-0}$$(x-0)$
$y-4=-2(x)$
$y+2x=4$
Hence (b) is the correct answer.
