Answer 1

In the context of the graph you provided, the dependent quantity is typically represented on the vertical axis (the y-axis), while the independent quantity is represented on the horizontal axis (the x-axis).

Here, the points are:

• (1,5)
• (2,6)
• (3,7)
• (4,8)

The first number in each pair (1, 2, 3, 4) represents the number of toppings, which is the independent variable. The second number (5, 6, 7, 8) represents the cost of a pizza, which depends on the number of toppings.

In this case, the dependent quantity is the cost of the pizza. Therefore, the numbers that represent the cost are 5, 6, 7, and 8.

Among the options provided, the number 7 represents a dependent quantity on the graph.

So the answer is 7.
