Identify the missing information of the following statement.

The relationship between the age of the child and the child's shoe size is  .

  1. positive
  2. negative

Explanation: Looking at the graph, first identify the points. Screen shot 2016 07 12 at 11.54.31 am There are sixteen points: (2,1), (3,1), (3,2), (4,3), (5,5), (5,6), (6,4), (6, 7), (7,6), (7,7), (8,6), (8,7), (8,9), (9,9), (10,9), (12,9) The line of best fit can be drawn on the image and it would have a positive slope. It is seen that as the age of the children increases that the shoe size also increases. Therefore there is a positive relationship between the child's age and shoe size.
