what is the problem you are stuck on
OpenStudy (anonymous):
Which ordered pair is not a solution? y < -x + 4 y > 1/2x - 2
A) (0,2)
B) (1,3)
C) (-2,2)
D) (-1,-1)
OpenStudy (uri):
@mathstudent55 Help him,i have no idea about this.

y < -x + 4 y > 1/2x - 2
choose one of the equations to replace y
-x+4>1/2x-2
+2 +2
-x+6>1/2x
+x +x
6> 3/2x
6(2/3)=(2/3)3/2x
4=x
OpenStudy (anonymous):
choose either equation and plug 4 in for x to find y
y<-4+4
y<0
OpenStudy (anonymous):
lets put x in bot equations of y in all cases and see if it is true
1(0,2)
y<-0+4 ,y<4
y>1/2(0)-2=-2 true cos y=2
2 (1,3)
y<-1+4=3
y>1/2(1)-2=-3/2
since \[y<3\] and not \[y \le 3\]
so y is strictly less than 3 and not equal so this point is not the solution since y=3
