Linear Equations and Functions

The video tutorial explains how to determine the value of Y in a table using the equation y = 1.5x + 10. It demonstrates finding the value for a specific X value, represented by a red box, and shows how to solve the equation using order of operations. The method is then generalized for any X value.
