उत्तर
| 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.
