Question

See Fig.3.14, and write the following:

(i) The coordinates of B.

(ii) The coordinates of C.

(iii) The point identified by the coordinates (–3, –5).

(iv) The point identified by the coordinates (2, – 4).

(v) The abscissa of the point D.

(vi) The ordinate of the point H.

(vii) The coordinates of the point L.

(viii) The coordinates of the point M.

Answer 1

We need to consider the given below figure to answer the following questions.

(i) The coordinates of point B in the above figure is the distance of point B from xaxis and y-axis. Therefore, we can conclude that the coordinates of point B are (―5, 2).

(ii) The coordinates of point C in the above figure is the distance of point C from xaxis and y-axis. Therefore, we can conclude that the coordinates of point C are (5, ―5).

(iii) The point that represents the coordinates (―3, ―5) is E.

(iv) The point that represents the coordinates (2, ―4) is G.

(v) The abscissa of point D in the above figure is the distance of point D from the yaxis. Therefore, we can conclude that the abscissa of point D is 6.

(vi) The ordinate of point H in the above figure is the distance of point H from the xaxis. Therefore, we can conclude that the abscissa of point H is ―3.

(vii) The coordinates of point L in the above figure is the distance of point L from xaxis and y-axis. Therefore, we can conclude that the coordinates of point L are (0, 5).

(viii) The coordinates of point M in the above figure is the distance of point M from xaxis and y-axis. Therefore, we can conclude that the coordinates of point M are (―3, 0).
