the complete question in the attached figure
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
\(y*x=k \\ y=\frac{k}{x}\)
in this problem
we have
\(H*W=20*5\\ H*W=100\\ H=100/W\)
So
the w-axis is a horizontal asymptote
the H-axis is a vertical asymptote
therefore
the answer is the option
D. horizontal asymptote
