This graph shows a map of an island just off the coast of a continent. The point labelled B represents a major city on the coast. The distance between grid lines represents 1 km.

Point A represents a resort that is located 5 km East and 3km North of point B. The values 5 and 3 are the coordinates of point A. The coordinates can be given as the ordered pair (5,3), where 5 is the horizontal coordinate and 3 is the vertical coordinate.

(ii) Mark the point that is 7km East and 5km North of point B and labels it C. Then, mark the point that is 5km East and 7km North of point B and label it D. Are points C and D in the same place? Give the coordinates of points C and D.

Answer 1

No, they are not in the same place. The coordinates of point C and D are (7,5) and (5,7), respectively.
