( (2 – 2)(y - 1214. Using the equation1 find the vertices. Select all that apply.94(21 + a, yı) and (x1 - a, yı)(1,5)(1, - 1)0 (-1,1)0 (-1, -1)(5,1)

we have the equation
[tex]\frac{(x-2)^2}{9}-\frac{(y-1)^2}{4}=1[/tex]this equation represent a horizontal hyperbola
so
a^2=9
a=3
b^2=4
b=2
(h,k)=(2,1)
so
x1=2
y1=1
x1+a=2+3=5
x1-a=2-3=-1
therefore
we have
