Here the coefficient of $x$ is negative.

Hence the parabola opens towards the left.

On comparing this equation with $y_{2}=−4ax$

$−4a=−8$

$⇒a=2$

$∴$ Coordinates of the focus $=(−a,0)=(−2,0)$

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

Equation of directrix $x=a$ i.e.,$x=2$

Length of latus rectum $=4a=8$
