<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:

We know that perpendicular lines have slopes which are negative inverses of each other. This means that the slope of the line we are going to need to find is 3.
Now, we can use the point-slope formula to find the actual equation of the line we are trying to find. The point-slope formula is
, where 
and 
are the coordinates of a point on the line and m is the slope.
Thus, the equation of the line we are trying to find is:
(y - 7) = 3(x - 2)
y - 7 = 3x - 6
y = 3x + 1
However, this is not an answer choice. The answers given have the constant on the right side of the equation. Thus, we will make our answer have the constant on the right side:
y - 3x = 1
-3x + y = 1
3x - y = -1
This is an answer choice. B, or 3x - y = -1 is the correct answer.
