A student is revising the basic ideas of the Cartesian plane.
(i) Define abscissa and ordinate of a point on the Cartesian plane.
(ii) Describe step-by-step how you would locate the point P(−3,4) starting from the origin.
(iii) A point Q has abscissa 0 and ordinate −5. State whether Q lies on an axis, in a quadrant, or at the origin. Give reasons for your answer.
(iv) Explain why the coordinates of a point do not change even if the same graph is drawn on paper of a different size.
