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 co-ordinates 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 co-ordinate 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)
Co-ordinates 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 x-axis, take 5 units to the right of the y-axis and then on the y-axis, take
2 units above the x-axis.
Therefore, we get the point A (5, 2).
(ii) B (-2, 4)
Co-ordinates 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 x-axis, take 2 units to the left of the y-axis and then on the y-axis,
take 4 units above the x-axis.
Therefore, we get the point B (-2, 4).
(iii) C (-4, -6)
Co-ordinates 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 x-axis, take 4 units to the left of the y-axis and then on the y-axis, take
6 units below the x-axis.
Therefore, we get the point C (-4, -6).
(iv) D (4, -3)
Co-ordinates 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 x-axis take 4 units to the right of the y-axis and then on the y-axis,
take 3 units below the x-axis.
Therefore, we get the point D (4, -3).
