This set of Mathematics Multiple Choice Questions & Answers (MCQs) focuses on “Coordinates and Quadrants – 1”.

1. Find the coordinates of point A and B as given in the figure.

a) A(4, 6) and B(4, 6)

b) A(-4, 6) and B(4, -6)

c) A(-4, -6) and B(4, 6)

d) A(4, -6) and B(-4, 6)

View Answer

Explanation: Point A is in 2

^{nd}quadrant with coordinates (-4, 6) and Point B is in 4

^{th}quadrant with coordinates (4, -6).

2. Identify the quadrant of point Q.

a) I

b) II

c) III

d) IV

View Answer

Explanation: The axes divide the plane into four parts called quadrants which are numbered in anticlockwise direction as I, II, III, IV. The point Q lies in III quadrant with coordinates (-4, -5).

3. The ordinate and abscissa of point A are ______________

a) 2, 3

b) 3, 2

c) 2, 2

d) 3, 3

View Answer

Explanation: The y-coordinate is called as ordinate and x-coordinate of a point is called abscissa. The ordinate and abscissa of point A are 2 and 3 respectively.

4. What is the sum of abscissas of point A and B?

a) 7

b) 2

c) 9

d) 3

View Answer

Explanation: Coordinates of point A and B are (2, 2) and (6, 4) respectively.

Abscissa of point A = 2

Abscissa of point B = 5

Sum of abscissas of A and B is 7.

5. What is the sum of abscissa and ordinate of point P and point Q?

a) 2

b) 1

c) 0

d) -1

View Answer

Explanation: Coordinates of point P are (3, 4) and that of point Q are (-5, -3).

Abscissa of P = 3

Ordinate of Q = -3

Sum = 3 + (-3) = 0.

6. What is the sum of y-coordinates of point G and H?

a) 6

b) -6

c) 3

d) -3

View Answer

Explanation: Coordinates of point G and H are (4, -2) and (-2, -4) respectively.

y-coordinate of G = -2

y-coordinate of H = -4

Sum = (-2) + (-4) = -6.

7. What will be the ordinate of P if sum of abscissa of P and abscissa of Q is 9?

a) 2

b) 9

c) 4

d) 3

View Answer

Explanation: Coordinates of point Q = (6, 6).

Abscissa (x-coordinate) of Q = 6

Sum of abscissa of P and abscissa of Q = 9

Abscissa of P = 9 – 6 = 3.

8. Calculate the length of Line PQ.

a) 10

b) 9

c) 8

d) 7

View Answer

Explanation: Coordinates of P = (-3, 4)

Coordinates of Q = (7, 4)

Length of line PQ = x-coordinate of P + x-coordinate of Q

= 3 + 7 = 10 units.

9. Find the coordinates of a point which is at a distance of 4m to the right of A and 2m above A.

a) (0, 7)

b) (2, 7)

c) (7, 7)

d) (2, 4)

View Answer

Explanation: Coordinates of A = (3, 5)

Abscissa of new point = Abscissa of A + 4 = 3 + 4 = 7

Ordinate of new point = Ordinate of A + 2 = 5 + 2 = 7

Coordinates of new point = (7, 7).
