# Linear Curve A linear bonding curve has a straight-line or additive relationship between successive trades and price. As an NFT is bought(sold), the next price it quotes to sell NFTs at will increase(decrease) by a flat amount (known as **delta**). 1. As an item is bought from the pool, the price will increase by a fixed amount. The reverse happens when an item is sold into the pool. 2. For example, if the delta is `0.2`, and the initial price is `1.0`. After someone buys 1 NFT from the pool, the price will be `1.2`. If someone sells an NFT into the pool, the price will be `0.8`. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
