Answer 1

Answer:

Step-by-step explanation:

Answer 2

$\large{\underline{\boxed{\purple{ANSWER}}}}$

The line 2x - ky + 6 = 0 passes through (2 , -8)

therefore ,

$2(2) - k( - 8) + 6 = 0 \\ \\ = > 4 + 8k + 6 = 0 \\ \\ = > 10 + 8k = 0 \\ \\ = > 8k = - 10 \\ \\ = > k = \frac{ - 10}{8} \\ \\ = > k = \frac{ - 5}{4}$
