Question

$If 3 x - 4 y + 5 = 0 and a x + 2 y + 4 = 0 are parallel to each other then a =$

Easy

Solution

$Two lines a_{1} x + b_{1} y + c_{1} = 0 and a_{2} x + b_{2} y + c_{2} = 0 are parallel if and only if \frac{a_{1}}{a_{2}} = \frac{b_{1}}{b_{2}}$
$It implies that \frac{3}{a} = \frac{- 4}{2}$
Cross multiply and then simplify
$\begin{matrix} - 4 a = 6 \\ a = - \frac{3}{2} \end{matrix}$
$Therefore, the value of a is a = - 1.5$

If 3x−4y+5=0 and ax+2y+4=0 are parallel to each other then a=

Two lines a1x+b1y+c1=0 and a2x+b2y+c2=0 are parallel if and only if a1a2=b1b2 It implies that 3a=−42Cross multiply and then simplify −4a=6a=-32 Therefore, the value of a is a=-1.5
