solve the system of equations by graphing. Then classify the system as consistent or inconsistent and the equations as dependent or independent.
x+y=14
xy=2
What is the solution of the system of equations?

I can not very well graph them here and see where they hit, but I can add them
2 x + y  y = 14 + 2
2 x = 16
x = 8
then
8 + y = 14
y = 6
so your lines should intersect at (8,6) 
re the two functions parallel, perpendicular, the same equation or none of these choices?
4x+4y=8
5x+5y=15
