The focus of the conic $x^{2}-6x+4y+1=0$ is

The locus of the poles of focal chords of the parabola $y^2 = 4ax$ is

$A$ circle of radius $4$,drawn on a chord of the parabola $y^2 = 8x$ as diameter,touches the axis of the parabola. Then,the slope of the chord is

The length of the latus rectum of the parabola $4y^2 + 2x - 20y + 17 = 0$ is

The equation of the tangent to the parabola $y^2 = 9x$ which passes through the point $(4, 10)$ is:

If the $x$-intercept of a focal chord of the parabola $y^2 = 8x + 4y + 4$ is $3$,then the length of this chord is equal to $.............$
