thanks for question Sharing

Answer 2

Answer:

We know that

$\frac{a1}{a2} = \frac{b1}{b2} = \frac{c1}{c2} \: (coincident \: lines)$

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

$\frac{a1}{a2} \: not \: equal \: to \: \frac{b1}{b2} \\ (intersecting \: lines)$

Then rearranging both equations,

$\frac{4}{1} \: not \: equal \: to \: \frac{2}{2}$

Hence it is a perpendicular lines

or intersecting lines
