Find an equation for the hyperbola described. Graph the equation. Center at (6, - 1); focus at (10, - 1); vertex at (9, - 1) Write an equation for the hyperbola. (Type exact answers for each term, using fractions as needed.) Select the graph which correctly describes the hyperbola. Solution [ (x - 6)^2 / 9 ] - [ (y + 1)^2 / 7 ] = 1 Option C.
