Practice the questions given in the worksheet on coordinate point. The questions are based on coordinate graph and how to locate the position of a point in a plane.
1. In which quadrant do the following points lie?
(i) A (3, 5)
(ii) B (-2, 1)
(iii) M (-1, -7)
(iv) N (4, -5)
(v) P (-1, 1)
(vi) Q (-5, 3)
(vii) R (7, -3)
(viii) S (4, 7)
2. State which of
the points lie on x-axis. Give a common reason.
(i) (0, 2)
(ii) (4, 0)
(iii) (0, 0)
(iv) (0, -3)
(v) (-5, 0)
(vi) (-1, 5)
(vii) (3, -1)
(vii) (2, 0)
3. State which of the points lie on y-axis. Give a common reason.
(i) (0, 4)
(ii) (7, 0)
(iii) (-5, 0)
(iv) (0, -3)
(v) (-1, 2)
(vi) (0, 0)
(vii) (0, 4)
(viii) (-6, -6)
4. Mark the following points on the graph.
(i) E (3, 7)
(ii) F (4, 0)
(iii) M (1, -3)
(iv) N (-2, 5)
(v) P (-1, -6)
(vi) Q (0, 8)
(vii) A (-4, 4)
(viii) B (2, -2)
5. XOX' and YOY' are the co-ordinate axes. Find out the co-ordinate of points, P, Q, R, S, T, U and V. Also write abscissa and ordinate in each case.
6. Plot the point P (4, 0), Q (4, 4), R (0, 4). Now join OP, PQ, QR, OR. What figure do you get?
7. On which axis do the following points lie.
(i) A (0, 4)
(ii) B (-5, 0)
(iii) C (2, 0)
(iv) D (0, 3)
(v) E (0, 0)
8. Write the following by observing the adjoining figure.
(i) Co-ordinates of A
(ii) Co-ordinates of B
(iii) Point identified by (-1, 2)
(iv) Point identified by (-2, -5)
(v) Abscissa of point C
(vi) Ordinate of point D
(vii) Abscissa of point E
(viii) Co-ordinates of point F
(ix) Point identifies by (-4, 4)
(x) Point having the co-ordinates (3, -3)
9. Write the co-ordinates of the points P, Q, R, S, T, U, V marked on the graph paper.
