A graph showing the cost of a pizza and the number of toppings has the following points: (1,5), (2,6), (3,7), (4,8). Identify which number represents a dependent quantity on the graph?
The dependent quantity on the graph is the cost of the pizza. This is because the cost of the pizza depends on the number of toppings. As the number of toppings increases, the cost of the pizza also increases.
