Question

need help
-5x+y<-2,
2x+y>-9
A
(–7, –1)
b(–1, –7)
c
(3, 5)
d(0, 3)

Answer 1

all you want to do is substitute ("plug") in the values that you are given into the two equations and find one which satisfies the equation. :)

For example... if we use option A which is (-7, -1) ---> x = -7 , y = -1 right?
So sub x = -7 and y = -1 into the equations :

-5x+y<-2

plug in x = -7, y = -1 and we get:

-5 ( -7) + (-1) < -2
35 - 1 < -2
34 < -2

Now note that "<" means is less than.
So is 34 LESS than -2?
