Answer
Asymptotes: $y=\displaystyle \frac{5}{3}x$ and $y=-\displaystyle \frac{5}{3}x$.
Foci: $(\sqrt{34}, 0)$ and $(-\sqrt{34}, 0)$.
Work Step by Step
The hyperbola
$\displaystyle \frac{x^{2}}{a^{2}}-\frac{y^{2}}{b^{2}}=1$
has a horizontal transverse axis and two asymptotes
$y=\displaystyle \frac{b}{a}x$ and $y=-\displaystyle \frac{b}{a}x$.
-----------
$a=3, \quad b=5$
For the foci,
$c^{2}=a^{2}+b^{2}=9+25=34$
$c=\sqrt{34}\approx 5.831.$
Vertices: $(3,\ 0)$ and $(-3,0)$.
Asymptotes: $y=\displaystyle \frac{5}{3}x$ and $y=-\displaystyle \frac{5}{3}x$.
Foci: $(\sqrt{34}, 0)$ and $(-\sqrt{34}, 0)$.
