HOw do you know when an equation has an infinite number of solutions?
Any single linear equation has an infinite number of solutions of the
form (x,y).
A system of 2 linear equations has an infinite number of solutions if
one of the equations is a multiple of the other.
------------------------------------------------------
How do you know when an equation has no solution
A system of 2 linear equations has no solution if
the slopes are equal and the y-intercepts are not equal.
