Question

II SHORT ANSWER TYPE QUESTIONS
13 While writing the coordinates of a point, which coordinate comes first: y-coordinate
or x-coordinate?
14 A policeman and a thief are equidistant from the jewel box. Upon considering jewel
box as origin, the position of policeman is (0, 5). If the ordinate of the position of
thief is zero, then write the coordinates of the position of thief.
15 Write two points lying on the x-axis, which are at equal distances from the origin.
16 In which quadrant, the points P(2, – 3) and Q(– 3, 2) lie?
17 Find the perpendicular distance of the point P(5, 7) from the x-axis
18 The point P(a, b) lies in the IVth quadrant. Which is greater: a or b?
19 Write the coordinates of a point whose abscissa is – 7 and ordinate is 2.
20 Which of the following points lie on the x-axis and which on the y-axis?
(0, –3), (–2, 0), (0, 5), (6, 0)
21 What is the sign of x-coordinate of a point lying in third quadrant?
22 If a point lies on the y-axis, then what will be its abscissa?
23 If the perpendicular distance of a point A from the x-axis is 6 units and foot of
perpendicular lies on the negative direction of the x-axis, then write the ordinate
of point A.
24 Write the coordinates of the following points. Also, Name the quadrants in which
they lie.
(i) the ordinate is 2 and the abscissa is – 3 (ii) the abscissa is – 4 and the ordinate is – 2
(iii) the ordinate is – 3 and the abscissa is 4 (iv) the ordinate is 3 and the abscissa is – 2
25 If the coordinates of two points are P(–2, 3) and Q(–3, 5), then find
(abscissa of P) – (abscissa of Q).
26 If the coordinates of two points P and Q are (2, –3) and (–6, 5) respectively, then
find the value of (y-coordinate of P) – (y-coordinate of Q).
27 Find the coordinates of a point:
(i) whose ordinate is 6 and lies on the y-axis
(ii) whose abscissa is –3 and lies on the x-axis.
