Final answer:
The firm's iso-costs line shows all combinations of two inputs that yield the same total cost.
Step-by-step explanation:
The firm's iso-costs line shows all combinations of two inputs that yield the same total cost.
For example, let's say a firm can produce 10 units of output with 2 units of labor and 3 units of capital or with 3 units of labor and 1 unit of capital. Both combinations would have the same total cost.
The iso-costs line helps firms determine the efficient allocation of inputs in order to minimize costs while producing the desired level of output.
