In mathematics, the abscissa (/æbˈs?s. ?/; plural abscissae or abscissæ or abscissas) and the ordinate are respectively the first and second coordinate of a point in a coordinate system. Usually these are the horizontal and vertical coordinates of a point in a two-dimensional rectangular Cartesian coordinate system.Click to see full answer. Also question is, what is an ordinate in math?The ordinate is the y-coordinate of a point on the coordinate plane. The distance along the vertical (y) axis. The x-coordinate of a point is called the “abscissa”. For more see Coordinates of a point. what is abscissa in math with example? The horizontal (“x”) value in a pair of coordinates. How far along the point is. Always written first in an ordered pair of coordinates such as (12,5). In this example, the value “12” is the abscissa. Also to know is, what is called abscissa? Abscissa. The abscissa is the x-coordinate of a point on the coordinate plane. The distance along the horizontal axis. Pronounced “ab-siss-ah” (the ‘c’ is silent). The y-coordinate of a point is called the “ordinate”.How do I remember ordinate and abscissa?Remember, if the distance of P from y-axis is ‘a’ and units the distance of P from the x-axis is ‘b’ units then the co-ordinates of point P are (a, b) where a denotes the x-co-ordinate or abscissa and b denotes the y-co-ordinate or ordinate.
