Step-by-step explanation:
A system that will produce infinitely many solutions will have the property where all the equations overlap. That means they will have the same slope and y-intercept.
An easy way to determine if they will produce infinitely many solutions is to put all the equations into

form. If everything is the same, you know it will have infinite solutions.
