Question

Following pairs of linear equation intersect at a point are parallel or coincident
=
$5x - 4y + 8 = 0 \\ 7x + 6y - 9 = 0$

Answer 1

Here #is ur answer. Hope it helps

Answer 2

the following pairs of linear equation is verified by method of
a1/a2,b1/b2,c1/c2
if a1/a2=b1/b2not equals to c1/c2 then it is parallel
if a1/a2 not equals to b1/b2 then it is intersect
if a1/a2=b1/b2=c1/c2 then it is coincident
