Vertices: $(±3,0)$ Asymptotes: $y=±\frac{4}{3}x$
Standard form when transverse axis is horizontal: $\frac{x^2}{a^2}-\frac{y^2}{b^2}=1$ $a^2=9$ $a=3$ $b^2=16$ $b=4$ Vertices when transverse axis is horizontal: $(±a,0)=(±3,0)$ Asymptotes when transverse axis is horizontal: $y=±\frac{b}{a}x$ $y=±\frac{4}{3}x$
