Does a horizontal line have horizontal asymptotes?

[Esoremada]

For example, y = 7. Are there an infinite number of asymptotes at any y value that isn't 7? If so, how would I format this statement on my homework?

*edit* oops sorry, I meant to post this in homework help

I don't think so.

Asymptotes are usually defined as lines that a given function approaches infinitely close, but never reaches. Under this definition, a line has no asymptotes.

Asymptotes are usually defined as lines that a given function approaches infinitely close, but never reaches.

Except functions like $\frac{\sin x}{x}$ cross their asymptote an infinite number of times.

Formal definition from Wikipedia:

Let $A:(a,b)\rightarrow\mathbb{R}^2$ be a parametric curve, in coordinates $A(t)=(x(t),y(t))$. Suppose the curve tends to infinity, that is:
$\lim_{t\rightarrow b}(x^2(t)+y^2(t))=\infty$.
A line $\mathcal{l}$ is an asymptote of A if the distance from A(t) to $\mathcal{l}$ tends to zero as $t\rightarrow b$

This is really iffy. You could argue either way.
