Write L if the equation is linear and write NL with reason if the equation is not linear.

1)
[tex]x + y = 5 [/tex]
2)
[tex]2x + {y}^{3} = 10[/tex]
3)
[tex]y = - 8x + \frac{1}{3} [/tex]
4)
[tex]y = { - x}^{ - 1} + 2 [/tex]
5)
[tex]x + \frac{2}{7} y = 5[/tex]
6)
[tex] \sqrt{ - 5} x + y = 1[/tex]
7)
[tex]x + \sqrt{y} = 2[/tex]
8)
[tex]y = { - x}^{ \frac{1}{5} } + 2[/tex]
9)
[tex]y = { - x}^{ \frac{a}{a} } + 2[/tex]

10)
[tex] \sqrt{4} x + y = 3[/tex]
