Tutorial - Determine if the equation has y varying directly with x ex 3, y = kx; y + 3 = -x

The video tutorial explains how to determine if an equation represents direct variation, where Y varies directly with X. It highlights the importance of equation formats and identifies red flags, such as additional terms, that indicate non-direct variation. The tutorial demonstrates why certain manipulations, like subtraction or division, cannot transform a non-direct variation equation into a direct one. An example is provided to illustrate a non-direct variation scenario, concluding with a summary of key points.
