Now we can see below illustration that there exists a linear relationship between the x and y-axis. Starting with the value of x from 0 to 3: Let’s say we want to plot it for four coordinate pairs. Now we want to plot it on the x and y-axis. Demonstrating Linearity Relation Between X and Y Axis In this region, the value of numbers lying on the x-axis is positive while the value of numbers lying on the y-axis is negative. The bottom right portion of the graph is known as the fourth quadrant. In this region, the value of numbers lying on the x-axis is negative while the value of numbers lying on the y-axis is also negative. The bottom left portion of the graph is known as the third quadrant. In this region, the value of numbers lying on the x-axis is negative while the value of numbers lying on the y-axis is positive. The top left portion of the graph is known as the second quadrant. In this region the value of numbers lying on x and y on both axes are positive. The top right portion of the graph is known as the first quadrant. The above figure shows the illustration of quadrants So there are four quadrants depending upon the positive and negative values of x and y. L d.X and Y axis divide the coordinate plane into four different halves which are referred to as quadrants. 3.2, the point identified by the coordinates (–5, 3) is a. The points whose abscissa and ordinate have different signs will lie in a.Abscissa of a point is positive in I and IV quadrants In the Cartesian plane, the horizontal line is called the x-axis and the vertical line is called the y-axis. NCERT Exemplar Class 9 Maths Exercise 3.1 Problem 17 Abscissa of a point is positive in a. ☛ Also Check: NCERT Solutions for Class 9 Maths Chapter 3 The quadrants are numbered in a counter clockwise direction. Therefore, the abscissa of a point is positive in I and IV quadrants. The abscissa is the horizontal direction (x) and the ordinate is the vertical direction (y). The abscissa is positive in the I and IV quadrant We know that the signs of the coordinates are The abscissa and ordinate together are called the rectan- gular or. Question Abscissa of a point is positive in A and II quadrants B I and IV quadrants C I quadrant only D II quadrant only Solution The correct option is B I and IV quadrants In the coordinate system, the ordinate is the second component of an ordered pair. Ordinate is the distance of point from x axis scaled with y axisīoth abscissa and ordinate are together known as coordinates If the first component is positive, the point lies to the right of the vertical axis. To understand how to plot a point in the four quadrants, we need to observe the signs of an x-coordinate (also called abscissa) and a y-coordinate (also called ordinate). The quarter plane that results from the division of the plane by the coordinate axes is called a quadrant. The point of intersection of the axes of coordinates is called the origin. The first coordinate x is called the abscissa while the second coordinate is called the ordinateĪbscissa is the distance of point from y axis scaled with x axis Abscissa and Ordinate in Quadrants The numbers in the quadrant are expressed in the ordered pair (a, b) where a is the x- coordinate and b is the y-coordinate. The abscissa and ordinate of a point taken together are known as coordinates of a point. In the coordinate (x, y) is used to denote the point in the cartesian plane
