Question

the line represented by 2x+3y-6=0 and 2x+3y+1=9 is which line????????

Answer 1

2x+3y-6=0,

2x+3y+1-9=0,
2x+3y-8=0,


here
a1=2, b1=3, c1=-6,

a2=2, b2=3, c2=-8,

hence

a1/a2 =2/2 = 1/1,

b1/b2 = 3/3 = 1/1,

c1/c2 = -6/-8 = 3/4,

since

a1/a2 = b1/b2 not equal to c1/c2,

therefore it represent a pair of parallel lines....
