KnowledgeBoat · Accepted Answer

(i) The abscissa is 2. The abscissa represents the x-coordinate, so x = 2. Observing the graph, the y-coordinate for this point is also 2. Hence, the point is A = (2, 2). (ii) The ordinate is 0. The ordinate represents the y-coordinate, so y = 0. Observing the graph, the x-coordinate for this point is 5. Hence, the point is B = (5, 0). (iii) The ordinate is 3. The ordinate represents the y-coordinate, so y = 3. Observing the graph, the x-coordinates for this point are -4 and 6. Hence, the points are C = (-4, 3) and E = (6, 3). (iv) The ordinate is - 4. The ordinate represents the y-coordinate, so y = - 4. Observing the graph, the x-coordinate for this point is 2. Hence, the point is D = (2, -4). (v) The abscissa is 5. The abscissa represents the x-coordinate, so x = 5. Observing the graph, the y-coordinates for this point are 0, 5 and -3. Hence, the points are B = (5, 0), H = (5, 5) and G = (5, -3). (vi) The abscissa is equal to the ordinate. The abscissa represents the x-coordinate, and ordinate represents the y-coordinate so x = y. Observing the graph, the points are (2,2), (5, 5) and (4, 4). Hence, the points are A = (2, 2), H = (5, 5) and I = (4, 4). (vii) The ordinate is half of the abscissa. The abscissa represents the x-coordinate, and ordinate represents the y-coordinate so y = . Observing the graph, the point is (6, 3). Hence, the point is E = (6, 3).
