Question

Select the correct option from the given alternatives:

If kx + 2y − 1 = 0 and 6x − 4y + 2 = 0 are identical lines, then determine k

Options

• −3

• `-1/3`

• `1/3`

• 3

Answer 1

−3

Explanation:

Lines kx + 2y − 1 = 0 and 6x − 4y + 2 = 0 are identical.

∴ `"k"/6=2/(-4)=(-1)/2`

∴ k = −3
