Solving linear systems 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.
No Solution:Two linear equations are parallel to each other. It is an inconsistent system.
Infinite Solution:

1.
Graph the following linear equations and find the point of intersection. State the consistency.
