Question

Match the coordinates given in Column A with the items mentioned in Column B.

Column A	Column B
(1) (0, 5)	(a) y coordinate is 2 × x - coordinate + 1.
(2) (2, 3)	(b) Coordinates of origin.
(3) (4, 8)	(c) Only y–coordinate is zero.
(4) (3, 7)	(d) The distance from x-axis is 5.
(5) (0, 0)	(e) y coordinate is double of x-coordinate.
(6) (5, 0)	(f) The distance from y-axis is 2.

Answer 1

Column A	Column B
(1) (0, 5)	(d) The distance from x-axis is 5.
(2) (2, 3)	(f) The distance from y-axis is 2.
(3) (4, 8)	(e) y coordinate is double of x –coordinate.
(4) (3, 7)	(a) y coordinate is 2 × x - coordinate + 1.
(5) (0, 0)	(b) Coordinates of origin.
(6) (5, 0)	(c) Only y–coordinate is zero.

Explanation:

(1) In the pair (0, 5), the second number also known as ordinate represents the distance from x-axis, i.e. 5.

(2) In the pair (2, 3), 2 the first number, also known as abscissa represents the distance from y-axis that is 2.

(3) We have the coordinates (4, 8). Clearly, coordinate is double of x-coordinate.

(4) We have the coordinate (3, 7), where x-coordinate = 3 and y-coordinate = 7

Evidently, y-coordinate = 2 × x-coordinate + 1

(5) (0, 0) are the coordinates of origin.

(6) In the point (5, 0), the y-coordinate is zero.
