Answer:

Horizontal asymptote: #y=0#

Explanation:

The only horizontal/slant asymptote is a horizontal asymptote at #y=0#. This is because the degree on the numerator (0) is less than the degree on the denominator (1).

Answer:

Vertical asymptote: x = 1; and horizontal asymptote: y = 0.

Explanation:

graph{y(x-1)-5=0 [-10, 10, -5, 5]}

The general equation of a rectangular hyperbola with center at #(

alpha, beta ) and m as the slope of one of the asymptotes is

#((y-beta)-m(x-alpha)((m(y-beta)+x-alpha)# = constant.

The asymptotes are given by

#y-beta=m(x-alpha) and x-alpha + m(y-beta)=0#

Here, it is # y(x-1)=5#. So, the asymptotes are given by

#x-1=0 and y = 0.

For this answer, I recalled from my memory what I had learnt, more

than 60 years ago. The graph affirms that I am right.
