Question

4. For what value of k, do the equations 3x – y +8 = 0 and 6x – k y = - 16 represent coincident lines?

Answer 1

Answer:

2

Step-by-step explanation:

3x - y + 8 = 0

6x - ky + 16 = 0

For coincident lines,

a1/a2 = b1/b2 = c1/c2

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

Considering 3/6 = -1/-k

1/2 = 1/k

k = 2

Thus, for k = 2, the given equations represent coincident lines.
