Question

on comparing the ratio a1/a2, b1/b2 and c1/c2 find out whether the lines represending the following pair of linear equations intersect at a point ,are parallel or coincident .
2x+4y-12=0 and x+2y-4=0​

Answer 1

Answer:

$\frac{a1}{a2} = \frac{2}{1} = 2 \\ \frac{b1}{b2} = \frac{4}{2} = 2 \\ \frac{c1}{c2} = \frac{ - 12}{ - 4} = 3$

it means lines are parallel

Answer 2

Answer:

this is correct...........................
