How to Identify an Increasing Linear Function

The video tutorial discusses increasing linear functions, starting with a question about identifying such functions from a set of graphs. It explains the definition of a linear function as a straight, non-vertical line on a coordinate plane and distinguishes between linear and non-linear graphs. The tutorial then focuses on identifying increasing linear functions by examining the slope of the line, concluding that a positive slope indicates an increasing function. The video ends with a summary of the key points and encourages continued learning.
