The locus of the point of intersection of the lines
and
is a hyperbola of eccentricity
Given: A hyperbola is formed by the locus of the point of intersection of lines ![]()
To find: Eccentricity of the hyperbola
![]()
![]()
Multiply by λ:
![]()
Adding (1) and (2):
![]()
![]()
![]()
![]()

![]()
![]()
Now, From (1):

![]()
![]()
![]()
![]()
![]()
![]()
![]()
![]()
Squaring both sides:

![]()
![]()
![]()
![]()
![]()
![]()
From (3) and (4):
![]()
![]()
![]()

Formula used:
For hyperbola ![]()
Eccentricity(e) is given by,
![]()
![]()
![]()
![]()
![]()
⇒ c = 8
Therefore,
![]()
⇒ e = 2
Hence, eccentricity of hyperbola is 2
