Question

please try to make sure that you

Answer 1

They are Coincident lines, We can tell that in 2 ways,

In general If there are two equations such as,
ax + by + c = 0, and 
dx + ey + f = 0, Then,

If , a/d = b/e = c/f, Then they are coincident lines,

Here the two equations are 3x+ 4y = 2, and 6x + 8y = 4,

We can observe that, 3/6 = 4/8 = -2/-4 = 1/2, So they are Coincident Lines,

Now 2nd Method,
We can see that If we take 2 common on both sides in the second equation, We will get the first equation, Which means, Both are same lines, So they are Coincident lines, Proved Again,

So therefore the answer to your question is Coincident Lines,

Hope you understand, Have a great day !,
