Evaluating Linear Equations and Patterns

Mr. B explains how to create a table of values from a linear equation using the formula y=mx+b. He demonstrates this with two examples: Y = -3x + 1 and Y = 5x - 3, showing how to choose x-values, substitute them into the equation, and calculate corresponding y-values. The video emphasizes understanding the slope's role in determining the pattern of y-values.
