1) Using the equation find a, b, x1 and y1

Answer:
Step-by-step explanation:
The standard form equation of a hyperbola is
[tex]\frac{\left(x-h\right)^2}{a^2}-\frac{\left(y-k\right)^2}{b^2}=1[/tex]
Here:
Given the equation
[tex]\frac{\left(x-2\right)^2}{4^2}-\frac{\left(y-1\right)^2}{2^2}=1[/tex]
comparing with the standard form equation of a hyperbola
(x₁, y₁) = (h, k) = (2, 1)
a = 4, b = 2
Therefore,
