This Equation In ( X 0, Y 0) Is True For All Other Values On The Parabola And Hence We Can Rewrite With ( X, Y).
The directrix is perpendicular to the axis of symmetry of a parabola and does not touch the parabola. Given the equation of parabola: Find the focus, vertex and directrix using the equations given in the following table.

Determine The Horizontal Or Vertical Axis Of Symmetry.
A parabola is a curved shape where any point is at an equal distance from a fixed point, and a fixed straight line. On the parabola y 2 = 6 4 x, find the point nearest to the straight line 4 x + 3 y − 1 4 = 0. Comparing it with the standard equation, we get
Equations And Definitions For Finding The Focus & Directrix Of A Parabola Parabola:
For parabola y 2 = 16x, find the coordinates of the focus, the length of the latus rectum and the equation of directrix. How do you find directrix from vertex form? Compare the given equation with the standard equation and find the value of a.
The Locus Of A Point Which Is Equidistant From A Fixed Point (Called The Focus) And A Fixed Line (Called The Directrix) Is Called A Parabola.
One way we can define a parabola is that it is the locus of points that are equidistant from both a line called the directrix and a point called the focus.so each point p on the parabola is the same distance from the focus as it is from the directrix as you can see.
