Question

Let x be the price of a new car. Let n be the number of people willing to buy the car at price x. As the price of the car goes from $12,500 to $13,700, fewer people will be willing to buy the car. Choose the graph that shows the relationship between x and n.

Answer 1

As the price of the car increases, the number of people
willing to buy it decreases.

The line in the first graph ' A ' is doing that.
