Question

The point whose ordinate is 3 and which lies on the y-axis is

P(5, – 7) be a point on the graph. Draw the PM ⊥ y-axis. The coordinates of M are

See Fig. 3.11 and complete the following statements: (i) The abscissa and the ordinate of the point B are _ _ _ and _ _ _, respectively. Hence, the coordinates of B are (_ _, _ _). (ii) The x-coordinate and the y-coordinate of the point M are _ _ _ and _ _ _, respectively. Hence, the coordinates of M are (_ _, _ _). (iii) The x-coordinate and the y-coordinate of the point L are _ _ _ and _ _ _, respectively. Hence, the coordinates of L are (_ _, _ _). (iv) The x-coordinate and the y-coordinate of the point S are _ _ _ and _ _ _, respectively. Hence, the coordinates of S are (_ _, _ _).

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.
