Ca sa apartina graficului trebuie ca F(-1)=1 si F(-2)=0
f(-1)=-1(1-m)+m+2n-4=1
f(-1)=-1+m+m+2n-4=1
2m+2n-5=1
2m+2n=6
2(m+n)=6
m+n=3

f(-2)=0
f(-2)=-2(1-m)+m+2n-4=0
-2+2m+m+2n-4=0
3m+2n-6=0
3m+2n=6

Acum aflam n si m 

m+n=3 => m=3-n
3m+2n=6
3(3-n)+2n=6
9-3n+2n=6
9-n=6
-n=6-9
-n=-3
n=3
m=3-n => m=3-3 => m=0
