Quadrant I 

 Quadrant II 

 Quadrant III 

 Quadrant IV

solving simultaneously y=2 and x therefore equals -6. therefore the solution is in the top left quadrant. (since y is positive but x is negative).

solving t grapgically would just involve rearanging them both into the form y=mx +c and drwing them and seeing where they overlap.

that would give y=-x/2 -1   and y=2x+14
