Front

How do you graph a linear equation?

Back

By plotting points that satisfy the equation and connecting them with a straight line.

What does it mean if a system of equations has no solution?

Back

The lines are parallel and do not intersect.

Front

What does it mean if a system of equations has infinitely many solutions?

Back

The lines are the same, meaning every point on the line is a solution.
