Question

The line graph shows Kelly’s height from ages 8 to 12 Which list contains only independent quantities 8 , 9 , 11 , 128 , 48 , 9 , 5448 , 50 , 52 , 54 48 , 54 , 55 , 61

Answer 1

From the graph, the independent variable (located on the x-axis) is the age of Callie, and the dependent variable (located on the y-axis) is Callie's height. Then, the list that contains only independent quantities is:

8 , 9 , 11 , 12

because all of them are ages.
