Question

the coordinates of the ordinary are​

Answer 1

Step-by-step explanation:

Ordinary affine points have coordinates [x/z , y/z , 1] while points on the line at infinity have coordinates [x, y, 0]. In the ordinary affine plane a straight line has an equation ax + by + c = 0. ... This is the point at infinity on the line and has homogeneous coordinates [b, -a, 0].

Answer 2

The coordinates of ordinate are
(0,y)

Abscissa is x and ordinate is y.
