Question

For what value of k the following system has unique solution or represent intersecting lines:
kx+4y-3=0, 9x+ky-7=0​

Answer 1

Step-by-step explanation:

In Unique soulution

$\frac{a1}{a2} is \: not \: equal \: to \: \frac{b1}{b2}$

So

$\frac{k}{9} is \: not \: equal \: to \: \frac{4}{k} \\ \\ {k}^{2} is \: not \: equal \: to \: \sqrt{36} \\ k \: is \: not \: equal \: to \: - 6 \: or \: 6$
