| (e) (0, 9) | (vi) The abscissa is zero. |
| (f) (6, 3) | (iv) The abscissa is double the ordinate. |
Explanation:
(a) Clearly, the ordinate of the point (7, 0) is zero.
(b) In the point (11, 11), the ordinate is equal to the abscissa.
(c) In the point (4, 8), the ordinate is double of the abscissa.
(d) In the point (6, 2), the abscissa, i.e. x-coordinate is triple of the ordinate, i.e. y-coordinate.
(e) The abscissa of the point (0, 9) is zero.
(f) Clearly, the abscissa is double of the ordinate.
