The vertices at $(0, \pm 10)$ indicate that the hyperbola is vertical and the distance from the center to a vertex is 10, so $a = 10$ and $a^2 = 100$. The slope of the asymptotes for a vertical hyperbola is given by $\pm \frac{a}{b}$, so from $y = \pm \frac{5}{3}x$, we find $b = 6$ and $b^2 = 36$. Thus, the equation is $\frac{y^2}{100} - \frac{x^2}{36} = 1$.
