Explain what is wrong with the way Steve has written the coordinates. [2]

Mark scheme

Scheme	Marks	Comments
Reference to the coordinates being reversed e.g. The coordinates have been reversed	E1	Allow E1 for 5, 1 OR (5; 1).
Reference to the poor syntax e.g. He has used a semi colon instead of a comma He hasn’t written his coordinates in brackets	E1	Allow E1 for (1, 5). Allow E1 E1 for “it should be (5, 1)”. If no marks, award E1 E0 for reference to Steve plotting the point in the wrong place e.g. “he should have gone (1) across and then (5) up”. Plotting (1,5) with ‘(1,5)’ written alongside is E1 E0. Plotting (1,5) with no attempt at an explanation is E0 E0.
