# Solution of Two Linear Equations- Open Middle Problem

Using the Integers 0-9 (without duplication), provide four sets of points that represent two distinct lines.  These lines can be written as two linear equations.  Then provide a fifth point that represents the intersection (or solution) of those equations.

Line 1: (__, __) and (__, __)

Line 2: (__, __) and (__, __)

Solution (__, __)

Write the equation of both lines.
