The locus of a point P(α,β)P(\alpha, \beta) moving under the condition that the line y=αx+βy=\alpha x+\beta is a tangent to the parabola y2=4axy^2=4 a x is
View answer and explanation
Correct option: B
xy=ax y=a
Option B (xy=axy=a) is correct because the condition for tangency to the parabola y2=4axy^2=4ax gives the relation αβ=a\alpha \beta = a, leading to the locus xy=axy=a.
