Step-by-step explanation:
[tex]2x - y + 1 = 0\: \\ \: 8x - 4y - 5 = 0[/tex]
[tex] \frac{2}{8} = \frac{1}{4} = \frac{1}{ - 5} [/tex]
[tex] \frac{1}{4} = \frac{1}{4} = \frac{ - 1}{5} [/tex]
[tex] \frac{a1}{a2} = \frac{b1}{b2} \: \: not \: equal \: to \: \frac{c1}{c2} [/tex]
[tex]Hence \: \: these \: \: are \: \: parallel \\ \: \: lines \: \: (Inconsistent)[/tex]
Thank you..
