The video tutorial explains how to graph lines in standard form by identifying x and y-intercepts. It begins with an introduction to linear equations and their uses. The tutorial then provides a detailed example of graphing the equation 4x + 5y = 20 by finding intercepts and plotting points. Finally, it applies these concepts to a real-world problem involving seating arrangements at a dinner table, demonstrating how to determine possible combinations of adults and children that can fit.
