What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables.

Front

How do you determine if a system of equations has a unique solution, no solution, or infinitely many solutions?

Back

A unique solution occurs when the lines intersect at one point, no solution when the lines are parallel, and infinitely many solutions when the lines coincide.

Front

What does it mean for two lines to be perpendicular?

Back

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