A point moves in $x - y$ plane as per $x = kt$ , $y = kt (1 - α t)$ where $k and α$ are +ve constants. The equation of trajectory is :-

Answer:

Solution:

Eliminate time using the x-coordinate.

$t = \frac{x}{k}$

$y = k t (1 - α t)$

$y = x (1 - \frac{αx}{k}) = x - \frac{α x ^{2}}{k}$

Option A.
