<h2>Answer:</h2>
The line y=k-1/4a represent in y=a(x-h)^2+k is:
Directrix.
<h2>Step-by-step explanation:</h2>Directrix of a parabola--
A directrix is a line which is perpendicular to the axis of symmetry of a parabola and it does not touch the parabola.
Also, for the standard equation of the parabola i.e.
The equation of directrix of a parabola is given by:
