WebMay 1, 2024 · 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. Webon the directrix is the difference of the y -values: d = y + p. The distance from the focus (0, p) to the point (x, y) is also equal to d and can be expressed using the distance formula. d = √(x − 0)2 + (y − p)2 = √x2 + (y − p)2. Set the two expressions for d equal to each other and solve for y to derive the equation of the parabola.
