Before study about the meaning of Abscissa coordinate first it is necessary to know about the coordinate plane. A rectangular plane that is obtained from two number lines i.e. vertical number line and the horizontal number line is known as coordinate plane. We know that horizontal line is denoted by the x – axis which is also known as abscissa and vertical line is known as ordinate which is the y – axis. In case of horizontal line positive numbers are taken at right hand side and negative number are taken at left hand side. In the vertical number line upper side contains positive numbers and lower side contains negative numbers. The meaning of abscissa is the distance from the y -axis in the Cartesian coordinate system which is measured parallel to the x – axis.
A point in a plane which has coordinates (5, 3), so ‘5’ is abscissa of this coordinate plane.
Abscissa definition can be understood by definition given below;
let (8, 3) here first value is ‘8’ is considered as the abscissa and it is plotted on the horizontal axis in two dimensional coordinate system. The second element is 3 in the ordered pair is considered as ‘ordinate’ which is plotted on vertical line i.e. on y – axis.
Let we have to plotted the point (3, -5), this point lies in fourth quadrant. The point 3 represents the ‘abscissa’ and -5 represents the ‘ordinate’. The point is located in fourth quadrant. we know that in fourth quadrant abscissa is positive and ordinate is negative. So we can say abscissa meaning is x -coordinate. This is all about abscissa definition. In mathematics there are different types of Integration Rules.
