Question

For what value of k, for the equations 3x – y + 8 = 0 and 6x – ky = -16 represents coincident lines? (a) 12 (b) –12 (c) 2 (d) -2​

Answer 1

Answer:

the value of k should be (c) 2

Step-by-step explanation:

we know that it is coincident line then,

a1/a2=b1/b2=c1/c2

then,

3/6=1/k=-8/-16

=> 1/2=1/k=-1/-2

so the value of k should be 2
