Solve the system of equations by graphing. Then classify the system as consistent or inconsistent; and the equations as dependent or independent.
3u+v=18
3u=v+30
-----------
Solve each equation for "v":
v = -3u+18
V = 3u-30
----------------

---------
Slopes are different and intercepts are different so the system is consistent.
The lines meet in one point.
