Evaluating Linear Functions and Formulas

The video tutorial explains how to evaluate a formula by substituting numbers for variables. It uses the example of the formula y = MX - B, where M, X, and B are given specific values. The tutorial demonstrates how to substitute these values into the formula, perform multiplication and subtraction, and calculate the final result, which is y = 11.
