Correction number 5

Question : A coordinate grid has the following set of ordered pairs ( -2,-5 ), ( 0,-4 ), ( 3,0 ), ( 4,1 ), ( 5,2 ), ( 6,3) The point ( 0,-4 ) is out of place.

Answer : True ( 0,-4 ) is out of place because it does not join the diagonal line as you see. For

( 0,-4 ) to join the diagonal line it would have to be ( 0,-3 ).
