The vertices are (2,8) and (2,-2)
The foci are (2,3+sqrt41) and (2,3-sqrt41)
The equations of the asymptotes are (y=3+5/4(x-3))
and (3-5/4(x-3))

Explanation:

Looking at the equation it's an up-down hyperbola

The center of the hyperbola is (2,3)

The vertices are (2,8) and (2,-2)

The slope of the asymptotes ares (5/4) and (-5/4)

The equations of the asymptotes are (y=3+5/4(x-3))
and (3-5/4(x-3))

To calculate the foci, we need c=+-sqrt(16+25)=sqrt41

The foci are (2,3+sqrt41) and (2,3-sqrt41)
