Question

Which of the following points is a solution to the system of linear inequalities?
-2x+y<-1
3x+y>=-5
A.
(0, –6)
B.
(1, –9)
C.
(2, –11)
D.
(3, –15)

Answer 1

Just plug in the points respectively
In a coordinated pair, it's (x,y)
So for A, x=0 and y=-6
Solve for -2(0)+(-6)<-1 and 3(0)+(-6)>-5, and if it's true, that's the answer.
