Step-by-step explanation:
The shape of the supply curve for tickets to football games at a stadium with 70,000 seats would most likely be upward sloping or positively sloped.
The supply curve in economics shows the relationship between the price of a product and the quantity of that product that suppliers are willing and able to produce and sell. For tickets to football games, as the price of tickets increases, suppliers (the stadium) will be more willing and able to supply a larger quantity of tickets.
This is because as the price of tickets increases, it becomes more profitable for the stadium to sell tickets, and they will have an incentive to produce and sell more tickets. This results in an upward-sloping supply curve.
