(ii) coincident lines
(iii) parallel lines

Answer 1

Answer:

i) interesting lines.

a1/a2=\= b1/b2

3/5=|= 5/3

so your linear equation is 5x - 3y= 1

ii) coincidence lines.

a1/a2 = b1/ b2= c1/ c2

3/6 = 5/10= 1/2

1/2 = 1/2=1/2

so your linear equation is 6x - 10y =2.

iii) parallel lines

a1/ a2 = b1/b2 =|= c1/c2.

3/6=5/10 =|= 1/1

1/2= 1/2 =I= 1/1

so your linear equation is 6x -5y = 1.

Hence proved.
