Question 427737
Solve systems of equations by graphing.
x + y =9 
x - y = 3
-----
y = -x+9
y = x-3
-----
{{{graph(400,300,-10,10,-10,10,-x+9,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)
