(i) 3
(ii) 2
(iii) 3
(iv) fourth
(v) 4

Question 2.
Fill in the blanks by seeing the graph 12.6 given below :

(i) Abscissa___and ordinate__are of point P. Therefore, the coordinates of point P are ___
(ii) Abscissa__and ordinate___are of point Q. Therefore, the coordinates of point Q are___
(iii) x-coordinate___and y-coordinate ___are of point R. Therefore, the coordinates of point R are ___
(iv) x-coordinate___and y-coordinate___are of point S. Therefore, the coordinates of point S are___
Solution:
(i) 2, 1, (2, 1)
(ii) – 3, 2, (- 3, 2)
(iii) -4,-3, (- 4,- 3)
(iv) 3, – 2, (3, – 2)

Question 3.
Plot the following points on squared paper and check whether they all are situated on straight line.
(i) A(1, 1); B(1, 2); C(1, 3); D(1, 4)
(ii) K(1, 3); L(5, 3); M(5, 5); N(1, 5)
(iii) P(2, 6); Q(5, 5); Y(5, 3); Z(6, 3)
Solution:
(i)

Yes, all points are collinear i.e. situated on a straight line.
(ii)

No, all points are not situated on a straight line.
(iii)

No, all points are not situated on a straight line.

Question 4.
Draw the following graph 12.7 on graph paper, write the answer of the questions given below.
(i) Write the coordinates of vertices of parallelogram ABCD. Find the length of sides AB and DC.
(ii) Find the coordinates of vertices of triangle PQR also find the length of base PQ.

Solution:
(i) A → (1,5)
B → (5, 5)
C → (6, 8)
D → (2, 8)
Length of side AB = 4 units
Length of side DC = 4 units
(ii) P → (1, 1)
Q → (4, 1)
R → (1, 3)
Length of base PQ = 3 units
