Solving the intersection of two lines graphically: 2x-y=2 and x+2y=-9.

Graphing Linear Equations Now that we have solved equations in one variable, we will now work on solving equations in two variables and graphing equations on the coordinate plane. Graphs are very important for giving a visual representation of the relationship between two variables in an equation. First, let's get acquainted with the coordinate plane (or Cartesian graph).
