Answer:

Second Choice.

Step-by-step explanation:

[tex]y = mx + b[/tex]

That is the linear function. Any coefficients with higher degrees won't be considered as a linear function.

So we can cut out the first and last choice.

Then we have only two choices which are

[tex]y = \frac{x}{2} - 5 \\ y = \frac{2}{x} + 3[/tex]

The second equation is called Rational Function where a variable is a denominator.

Therefore, the correct answer is second choice.
