Graphing Linear Equations: Test Your Knowledge

The video tutorial covers graphing linear equations, starting with standard form and moving to slope-intercept form. It explains how to find x and y intercepts for standard form and how to use the slope and y-intercept for slope-intercept form. The tutorial also addresses special cases of vertical and horizontal lines, providing examples and step-by-step instructions for each method.
