Question

Check whether the lines represented by 2x+y=3 and 4x+2y=9 are parallel, coincident or intersecting

Answer 1

Answer:

a1/a2=2/4=1/2

b1/b2=1/2

c1/c2=3/9=1/3

So as we can see that,

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

So therefore,it is a 'no solution' which represents parallel lines....

Hope this helps you!

Answer 2

Answer:

parallel lines as a1 by a2 is equal to b1 by b2 but b1 by b2 is not equal to c1 by c2
