Solving systems of linear equations by graphing

In order to determine the number of solutions to a system of linear equations, other than by finding the slope of the lines, we can also graph the equations out and look for the intersection of the lines.

Notes:
One Solution: Two linear equations intersect at one point. It is a consistent system of independent equation.
system of linear equations with one solution
No Solution:Two linear equations are parallel to each other. It is an inconsistent system.
system of linear equations with two solutions
Infinite Solution:
