Mathematics - Straight Lines Question with Solution | TestHub

Given lines are $$ax+2by+3b=0\text{ and }$$ $$bx-2ay-3a=0$$ Since, required line is $\Vert$ to $x$-axis $$\therefore x=0$$ We put $x=0$ in given equation, we get $$2by=-3b\Rightarrow y=-\frac{3}{2}$$ This shows that the required line is below $x$-axis at a distance of $\frac{3}{2}$ from it.
