Understanding the Locus of Intersection Points
The problem involves finding the locus of intersection points of two lines influenced by a parameter 'k'. Let's analyze the equations given:
1. Line Equations:
- Line 1: √2x - y + 4√2k = 0
- Line 2: √2kx + ky - 4√2 = 0
2. Finding Intersection:
- To find the intersection, we solve these equations simultaneously. We can express 'y' from Line 1 and substitute it into Line 2.
Substituting and Rearranging
- From Line 1, we can express y as:
y = √2x + 4√2k
- Substitute this in Line 2:
√2kx + k(√2x + 4√2k) - 4√2 = 0
- This simplifies to:
(√2k + k√2)x + 4k^2 - 4√2 = 0
(2√2k)x + 4k^2 - 4√2 = 0
Resulting Equation
- From the above, rearranging gives us a quadratic in 'x' based on 'k', leading to:
x = (2√2 - 4k^2)/(2√2k)
Identifying the Locus
- As 'k' varies, the above expression describes a hyperbola. The key points here are:
- The hyperbola's transverse axis length and the eccentricity can be derived from the standard form.
- The transverse axis length is found to be 8√2.
Conclusion
Thus, the locus of the intersection points forms a hyperbola with a transverse axis length of 8√2. Hence, the correct answer is option 'C'.
