Question

the lines 2x-y+1=0 and 8x-4y-5=0 are parallel or perpendicular

please answer step by step ​

Answer 1

Step-by-step explanation:

$2x - y + 1 = 0\: \\ \: 8x - 4y - 5 = 0$

$\frac{2}{8} = \frac{1}{4} = \frac{1}{ - 5}$

$\frac{1}{4} = \frac{1}{4} = \frac{ - 1}{5}$

$\frac{a1}{a2} = \frac{b1}{b2} \: \: not \: equal \: to \: \frac{c1}{c2}$

$Hence \: \: these \: \: are \: \: parallel \\ \: \: lines \: \: (Inconsistent)$

Thank you..
