If one line is useful, let's see what we can do with two lines. In this unit, we learn how to write systems of equations, solve those systems, and interpret what those solutions mean in a real-world context.

Think of linear as just a line. A linear function is one that, when graphed, forms a line. Linear functions are in the form: f(x) = ax + b, where a and b are constants.

When solving systems of linear equations, one method is to graph both equations on the same coordinate plane. The intersection of the two lines represents a solution that satisfies both equations.
