TopicLinear Functions DefinitionAn increasing linear function is a linear function where the slope is positive, indicating that as the input value increases, the output value also increases. DescriptionIncreasing linear functions are essential in understanding how variables positively relate to each other. The positive slope signifies an increase in the dependent variable as the independent variable increases. Real-world examples include income increasing with hours worked or the rise in temperature with the increase in daylight hours. These functions help model scenarios where an increase in one quantity results in an increase in another. |
