If the quantity of wood purchased decreases when the price of wood rises, a graph representing these variables would have

D) a negative slope.

Question

Quizplus · Accepted Answer

When the price of wood rises, the quantity purchased decreases. This relationship between price and quantity is known as a negative or inverse relationship, meaning that as one variable increases, the other decreases. Therefore, the graph would have a negative slope, where the price of wood would be on the vertical axis and the quantity purchased on the horizontal axis. Time is not a relevant variable in this scenario, so B is not a valid choice. The slope is a measure of how steep a line is, and it would not make sense to have the slope on the vertical axis, so C is also not a valid choice.
