Question. Write whether the following statements are True or False? Justify your answer.
(i) Point (3, 0) lies in the first quadrant.
(ii) Points (1, –1) and (–1, 1) lie in the same quadrant.
(iii) The coordinates of a point whose ordinate is -1/2 and abscissa is 1 are (-1/2,1)
(iv) A point lies on y-axis at a distance of 2 units from the x-axis. Its coordinate are (2, 0).
(v) (–1, 7) is a point in the II quadrant.
Answer. (i) The point (3, 0) has abscissa 3, the x-coordinate and ordinate is 0. If the ordinate of a point is zero, the point lies on the x-axis.
Hence, the given statement is false.
(ii) The point (1, –1) lies in IV quadrant and the point (–1, 1) lies in II quadrant.
Hence, the given statement is false.
(iii) We know that in the coordinates of a point, the abscissa comes first and then the ordinate. So, the coordinate of a point are (1,-1/2) and not (-1/2,1)
(iv) Any point which lies on the y-axis is of the form (0, y).
Hence, the given statement is false.
(v) In the II quadrant, signs of abscissa and ordinate are –, + respectively.
Hence, the statement that (–1, 7) is a point in the II quadrant is a true statement.

Question. Without plotting the points indicate the quadrant in which they will lie, if
(i) ordinate is 5 and abscissa is – 3
(ii) abscissa is – 5 and ordinate is – 3
(iii) abscissa is – 5 and ordinate is 3
(iv) ordinate is 5 and abscissa is 3
Answer. (i) In the point (–3, 5) abscissa is negative and ordinate is positive, so it lies in the second quadrant.
(ii) In the point (–5, –3) abscissa and ordinate both are negative, so it lies in the third quadrant.
(iii) In the point (–5, 3) abscissa is negative and ordinate is positive, so it lies in the second quadrant.
(iv) In the point (3, 5) abscissa and ordinate both are positive, so it lies in the first quadrant.
