How to plot ordered pairs in an exact quadrant on a graph paper?
The method of plotting a point on the graph paper, if its coordinates are known to us. Click here to know the method of plotting the ordered pairs on the graph paper.
The examples will help us to draw or construct coordinate graph in exact quadrant.
Plot each of the following points on a graph paper:
(i) A (5, 2)
(ii) B (2, 4)
(iii) C (4, 6)
(iv) D (4, 3)
Solution:
Let X'OX and YOY' be the coordinate axes.
(i) A (5, 2)
Coordinates of the point A are (5, 2); both abscissa and ordinate are positive so the point A (5, 2) lies in the first quadrant. On xaxis, take 5 units to the right of the yaxis and then on the yaxis, take
2 units above the xaxis.
Therefore, we get the point A (5, 2).
(ii) B (2, 4)
Coordinates of the point B are (2, 4); the abscissa of the point is negative and the ordinate of the point is positive so the point B (2, 4) lies in the second quadrant. On the xaxis, take 2 units to the left of the yaxis and then on the yaxis,
take 4 units above the xaxis.
Therefore, we get the point B (2, 4).
(iii) C (4, 6)
Coordinates of the point C are (4, 6); both abscissa and ordinate are negative so the point C (4, 6) lies in the third quadrant. On the xaxis, take 4 units to the left of the yaxis and then on the yaxis, take
6 units below the xaxis.
Therefore, we get the point C (4, 6).
(iv) D (4, 3)
Coordinates of the point D are (4, 3); the abscissa of the point is positive and the ordinate of the point is negative so the point D (4, 3) lies in the fourth quadrant. On the xaxis take 4 units to the right of the yaxis and then on the yaxis,
take 3 units below the xaxis.
Therefore, we get the point D (4, 3).
