What is vertical asymptote of y=2x+1?
I don't know how to find it.

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

Math 
Reiny,
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
