WebOct 6, 2024 · Key Concepts. A parabola is the set of all points (x,y) in a plane that are the same distance from a fixed line, called the directrix, and a fixed point (the focus) not on the directrix. The standard form of a parabola with vertex (0,0) and the x -axis as its axis of symmetry can be used to graph the parabola. http://endmemo.com/algebra/parallellinepoint.php
