put x=0 at eq 1 y>=1
OpenStudy (anonymous):
how
OpenStudy (anonymous):
if x=0 then y should be 1
OpenStudy (anonymous):
y >=1
OpenStudy (anonymous):
i dont know wht i do with that though

okay.......
first line (first eq)
if x=0 then y>= -3(0)+1>=1
ifx=1 then y>= -3(1)+1>=-2
OpenStudy (anonymous):
any value that put y less then these numbers is out of the system
OpenStudy (anonymous):
you could the same thing of the other eq.
OpenStudy (anonymous):
\[y \ge \frac{ 1 }{ 2 }(0)+3\]
OpenStudy (anonymous):
thats what youre saying right

when x=0 the y >=1
OpenStudy (anonymous):
so i was wrong?
OpenStudy (anonymous):
no......
1)- first line y>=-3x+1 if x=0 then y>=1, x=1 then y>=-2
2)- second line y>=1/2x+3 if x=0 then y>=3, x=1 then y>=3.5
