y = 2x + 1 is a straight line with a slope of 2

To be vertical the slope would have to be undefined, and the equation would have the form

x = k, where k is some constant.

no vertical asymptote.

Thank you~ and as for horizontal, the asymptote would be y=0?

We don't actually speak of asymptotes for straight lines

but, yes, a horizontal asymptote would have the form

y = k, where k is a constant
