What is a system of linear equations?

Back

A set of two or more linear equations with the same variables. Solutions are the points where the equations intersect on a graph.

Front

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

Back

It means that the equations represent the same line, and every point on that line is a solution.

Front

How can you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope and different y-intercepts.

Front

What does it mean if two lines are perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.
