a. Conic.
b. Focus
c. Directrix
Explanation of Solution
Given:
A____ is the set of points in a plane such that the ratio of the distance from a fixed point called the______ to to the distance from a fixed line called the ______equals a constant .
Calculation:
A conic is the set of points in a plane such that the ratio of the distance from to to the distance from to equals where is the focus, the point and is the directrix, the fixed line.
That is, a conic is the collection of points for which
