Explanation Given: An hyperbola with focus ( 9 , 0 ) , directrix x = 4 and a point on hyperbola ( 9 , − 7.5 ) . Definition used: The distance between two points P ( x 1 , y 1 ) and F ( x 2 , y 2 ) is d ( P , F ) = ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2 . The perpendicular distance D from a point P ( x 1 , y 1 ) to a line x = a is D = | x 1 − a | . The eccentricity e of an hyperbola is calculated by e = P F D . Here, P F is the distance from a point on hyperbola to the focus of hyperbola and D is the distance between the same point to directrix of the hyperbola. Calculation: The distance between focus F ( 9 , 0 ) of hyperbola and a point P ( 9 , − 7
