Not really, but...

#### Explanation:

Something vaguely similar that you can use for a line in any number of dimensions is a point-vector form, which you could write like this:

#underline(x) = underline(x_0)+tvec(v)#

In three dimensions:

#(x, y, z) = (x_0, y_0, z_0) + t(u, v, w)#

#= (x_0 + tu, y_0 + tv, z_0 + tw)#
