Abscissa of a point is positive in
I and IV quadrants
In the coordinate system, the ordinate is the second component of an ordered pair. For example, if is an ordered pair, then y is the ordinate here. An ordered pair is used to denote a point in the Cartesian plane and the first coordinate , in the plane, is called the abscissa.
The distance of a point from scaled with the is called abscissa or coordinate of the point. The distance of a point from scaled with the is called ordinate. The abscissa and ordinate all together are called coordinates.
Using the information, we can conclude the following:
The signs of the coordinates in
Hence, the abscissa of the point is positive in the first and fourth quadrant
So, the correct option is (b)
