The general equation of a conic is ax2 + 2hxy + by2 + 2gx + 2fy +c =0.

Here if e =1 where e is eccentricity  and D≠ 0, then it represents a parabola

The general equation of parabola is (y-y0)2 = (x-x0), which has its vertex at (x0, y0). 

The general equation of parabola with vertex at (0, 0) is given by y2 = 4ax, and it opens rightwards.  

The parabolax2 = 4ay  opens upwards.   

The equation y2 = 4ax is  considered to be the standard equation of the parabola for which the various components are        

Vertex at (0,0)               

Directrix is x+a = 0       

Axis is y = 0  

Focus is (a, 0)

Length of latus rectum = 4a         

Ends of latus rectum are L (a, 2a) and L’(a, -2a)

The parabola y = a(x – h)2 + k has its vertex at (h, k)

slope=tanθ=(y“-y’)/(x“-x’)=measure of inclination of the line with the positive x-axis. where (x’,y’) and (x“,y“) are the coordinate of any two points on the line.

If a line be drawn through the focus and parallel to the directrix, it will intersect the parabola at two points that lie a distance 2 p from the focus. The line segment connecting these two points is called the focal chord.
