If the transverse axis is horizontal, then we have the equation of a hyperbola as:

(x - h)^2 / a^2 - (y - k)^2 / b^2 = 1

where (h, k) is the center of the hyperbola, a is the distance from the center to the vertices, b is the distance from the center to the conjugate axis, and c is the distance from the center to each focus.

Given that a = 1 and c = 9, we need to find b. The relation between a, b, and c is given by the equation:

c^2 = a^2 + b^2

Substituting the given values:

(9)^2 = (1)^2 + b^2
81 = 1 + b^2
b^2 = 81 - 1
b^2 = 80
b = √80 = 4√5

So, the equation of the hyperbola becomes:

(x - h)^2 / 1^2 - (y - k)^2 / (4√5)^2 = 1

Simplifying further, we have:

(x - h)^2 - (y - k)^2 / 80 = 1

Note that without further information about the center and orientation of the hyperbola, we cannot determine the exact equation.
