Here, the coefficient of $y$ is negative.

Hence the parabola opens downwards.

On comparing this equation with $x_{2}=ā4ay$Ā

$ā4a=ā16$

$āa=4$

$ā“$Ā Coordinates of the focus $=(0,āa)=(0,ā4)$

Axis of the parabola is the $y$-axis i.e $x=0$

Equation of directrix Ā $y=a$ i.e., $y=4$

Length of latus rectum $=4a=16$
