How do you know when an equation has infinitely many solutions? How do you know when an equation has no solution?
------------------------------------
Assuming you are talking about linear equations:
infinitely many solutions if slopes and y-intercepts are equal.
------------
no solution if equal slopes and unequal y-intercepts.
