To determine which option is represented by a line that slopes upward from left to right on a market graph, we need to understand the fundamental concepts associated with each option:
1. Demand Curve: The demand curve typically slopes downward from left to right, indicating that as the price decreases, the quantity demanded increases, and vice versa.
2. Supply Curve: The supply curve usually slopes upward from left to right. This slope indicates that as the price increases, the quantity supplied increases as well. Producers are willing to supply more at higher prices because it is more profitable.
3. Price Axis: The price axis, typically the vertical axis, does not slope upward. It represents price levels on a vertical scale.
4. Quantity Axis: The quantity axis, typically the horizontal axis, does not slope upward. It represents quantities on a horizontal scale.
Given these descriptions, the correct answer is:
Supply curve
The supply curve is the line that slopes upward from left to right on a market graph.
