how to graph vertical lines of a linear equation, x = -1

The video tutorial explains how to graph vertical and horizontal lines, focusing on equations that cannot be expressed in the slope-intercept form Y = MX + B. The instructor emphasizes using a table of values to graph such equations, specifically demonstrating with X = -1. The tutorial highlights that when X equals a constant, it forms a vertical line, and when Y equals a constant, it forms a horizontal line. The video aims to help students recognize patterns in graphing these lines.
