The graphs of the equations 6x – 2y + 9 = 0 and 3x – y + 12 = 0 are two lines which are

Question

Philoid · Accepted Answer

We have,

6x – 2y + 9 = 0

And, 3x – y + 12 = 0

Here, a₁ = 6, b₁ = – 2 and c₁ = 9

a₂ = 3, b₂ = – 1 and c₂ = 12

∴ , and

Clearly,

Hence, the given system has no solution and the lines are parallel

∴ Option B is correct
