ummmm where?

@mathmath333
OpenStudy (mathmath333):
first identify the line
in the graph
\(y=x+1\) and \(y+x=-1\)
OpenStudy (sparklestaraa):
OHHH part D maybe

OpenStudy (sparklestaraa):
or C part C i go with c because -1 is in it
OpenStudy (mathmath333):
m not asking u the options ., m asking u to identify the two lines in the diagram
OpenStudy (sparklestaraa):
Honestly idk
OpenStudy (mathmath333):
the one which has point
\((0,1)\) and \((-1,0)\)
is \(y=x+1\) as if satifies the point
and the other one is \(y+x=-1\)
OpenStudy (sparklestaraa):
OHHHHHH its in A

OpenStudy (mathmath333):
how can u say that ?
OpenStudy (sparklestaraa):
its where those points are
OpenStudy (mathmath333):
i said that to find the eqution of line, it doesnt say thats the region.
OpenStudy (sparklestaraa):
Or u know it could be d idk because the little point is on the line between
OpenStudy (sparklestaraa):
Ohhhhhhhh ok wait

I swear idk what the equation of the line was
OpenStudy (mathmath333):
so try to put 4 points from each region
\((0,2) \)
\((2,0)\)
\((-2,0)\)
\((0,-2)\)
in the two inequalities and see which point it satisfies
OpenStudy (sparklestaraa):
how is that going to show me it just doesn't make sense ???
OpenStudy (mathmath333):
example
\((2,0)\)
\(0\geq 2+1\)
its false so option B is not true
OpenStudy (mathmath333):
as 0 is not greater than 3
