Question

The value of k for which the equations 3x – y + 8 = 0 and 6x + ky = - 16
represent coincident lines, is
1
(A)
2
1
(B)
2
(C) 2
(D) - 2​

Answer 1

Answer:

3x - y +8 =0

6x +ky = - 16

3x - y +8 =0

6x +ky +16 =0

a¹ = b¹ = c¹

a² b² c²

3 = - 1 = 8

6 k 16

1 = - 1 = 1

2 k 2

1 = - 1

2 k

k = - 2

(D) is the correct answer

= - 2
