Front

What does it mean for a system of equations to have infinitely many solutions?

Back

A system has infinitely many solutions when the equations represent the same line, meaning every point on the line is a solution.

Front

How can you determine if a system of equations has one solution?

Back

A system has one solution if the lines intersect at exactly one point, meaning they have different slopes.
