Practise the method.Example 1Find the midpoint of (−8,4) and (−2,14).Show worked answerAnswer: (−5,9)Average each coordinate: (2−8−2,24+14)=(−5,9).Example 2Find the gradient through (−5,3) and (1,15).Show worked answerAnswer: 2Gradient =change in xchange in y=612=2.Example 3Find the distance between A(4,4) and B(20,34), in coordinate units.Distances in coordinate unitsDistances in coordinate unitsPoint A is (4, 4) and point B is (20, 34). Horizontal change 16, vertical change 30. Diagram not to scale. Use the labelled measurements.1630xDiagram not to scaleShow worked answerAnswer: 34The horizontal and vertical changes are 16 and 30.Distance =√162+302=34 units.
