What is the labor-leisure mode?

What is the labor-leisure mode? How to use this model to push the personal labor supply curve?

(1) Labor and leisure

Labor supply involves the allocation of workers' given time and resources. Workers can be regarded as consumers, and their choice between leisure and labor is the choice between leisure and labor income to meet their desire to maximize utility.

(2) Using this model, the individual labor supply curve is deduced:

According to consumer theory, the demand for specific goods and services is influenced by many variables, the most important of which are the prices of goods and services, consumers' income and consumers' preferences for goods and services. Theoretical expectations: first, the higher the price of a commodity, the lower the consumer's demand for the commodity, all other things being equal; Second, if the goods are normal, if consumers' income increases, consumers' demand for the goods will increase; Third, when consumers' preferences change, consumers' demand for goods will also change.
