Algebra 2 - Determine if a function is an example of direct variation y‐1=x

The video tutorial explains how to determine if an equation is an example of direct variation. It involves solving for Y and checking if the equation is in the form of Y = kX, where k is a constant. The tutorial highlights that direct variation does not include any addition or subtraction of constants. The example given, Y = X + 1, is analyzed and determined not to be a direct variation due to the presence of the constant 1 added to X.
