The abscissa is also known as the "x" coordinate of a point, shown on the horizontal line, with the ordinate, also known as the "y" coordinate, shown on the vertical line. [First attested in the late 17^th century.][1]

   The point ${\displaystyle (3,2)}$ has 3 as its abscissa and 2 as its ordinate.

2. (geometry) The horizontal line representing an axis of a Cartesian coordinate system, on which the abscissa (sense above) is shown.

Originally, it referred to the portion of a line between a fixed point on that line and the intersection of that line with an ordinate.[1]
