Question 875389: find the center, foci, asymptotes and a graph the hyperbola in the space provided:
(x-2)^2/36 -(y-3)^2/25 =1
Please Help with this. I really need it. Thank you!

%28x-h%29%5E2%2Fa%5E2%22%22-%22%22%28y-k%29%5E2%2Fb%5E2 %22%22=%22%22 1

is the equation of a hyperbola like this " )( "

with center (h,k), semi-transverse axis = a, semi-conjugate axis = b

%28x-2%29%5E2%2F36%22%22-%22%22%28y-3%29%5E2%2F25 %22%22=%22%22 1

%28x-2%29%5E2%2F6%5E2%22%22-%22%22%28y-3%29%5E2%2F5%5E2 %22%22=%22%22 1

We 

1. Plot the center (2,3).
2. Draw the transverse axis (red) of 2a = 2(6) = 12
3. Draw the conjugate axis (blue) of 2b = 2(5) = 10,
4. defining rectangle (in green)
5. Draw and extend diagonals forming asymptotes (dotted lines),
6. Sketch the hyperbola.
7. Calculate c by c²=a²+b²=36+25=61, c=%22%22%B1sqrt%2861%29
8. Foci are (h±c,k) which are (2-sqrt%2861%29,3), (2+sqrt%2861%29,3), the big black dots.
9. Find equations of asymptotes.  Slopes are %22%22%2B-b%2Fa through (h,k)
                                  Slopes are (((""+-5/6}}} through (2,3)

Use point-slope formula:
y - y1 = m(x - x1)
where (x1,y1) = (2,3)
 
y - 3 = 5%2F6(x - 2)  and  y - 3 = -5%2F6(x - 2)

You can simplify those equations.
