Mathematics - Straight Lines Question with Solution | TestHub

Consider the lines $\mathrm{x}(3\lambda +1)+\mathrm{y}(7\lambda +2)=17\lambda +5$, $\lambda$ being a parameter, all passing through a point P . One of these lines (say L) is farthest from the origin. If the distance of $L$ from the point $(3,6)$ is $d$, then the value of $d^2$ is
