for this question. We want to know. Every linear function is also a direct variation. Creation some what we already know this After recreation equations fall, the form y equals K X. Only the equations for the form black was MX plus B. So you can see from this is that they fold the same form except K. Here is M here, so I will say direct variation were rewrite as y equals MX and linear equations will be. Why equals X Plus B? So we'll see that a linear equation is also direct variation equation on Lee If if and only if, b equals equals does not equal a Loretta's be equals zero, so therefore not all linear equations, our direct creations.
