A graph showing the cost of a pizza and the number of toppings has the following points: (1,5)%0D%0A(%0D%0A1%0D%0A,%0D%0A5%0D%0A)%0D%0A, (2,6)%0D%0A(%0D%0A2%0D%0A,%0D%0A6%0D%0A)%0D%0A, (3,7)%0D%0A(%0D%0A3%0D%0A,%0D%0A7%0D%0A)%0D%0A, (4,8)%0D%0A(%0D%0A4%0D%0A,%0D%0A8%0D%0A)%0D%0A. Identify which number represents a dependent quantity on the graph.%0D%0AResponses%0D%0A%0D%0A7%0D%0A7 - not selected, this is the correct answer%0D%0A%0D%0A1%0D%0A1 - no response given%0D%0A%0D%0A4%0D%0A4 - no response given%0D%0A%0D%0A3

The dependent quantity on the graph is the cost of the pizza. This is represented by the y-values in the points given: 5, 6, 7, and 8.
