Solve systems of equations by graphing.
x + y =9
x - y = 3
-----
y = -x+9
y = x-3

----
Then classify system
Is it consistent?:: Yes since the lines are not parallel.
------
Are equations dependent or independent?::Independent
because there are two lines to graph, not two of the
same line.
--------
Solution is ?::(6,3)
