Which point lies in the solution set for the following system of inequalities?
y < 2x + 4
y < -2x + 2

(1, 0)

(-5, -2)

(0, -3)

(-1, 5)

Answer 1

ok so basically all you need to do is plug in the points to x and y..
0<-2(1)+2
0<0 --> not true so A doesnt work...make sense?

Answer 2

yes

Answer 3

ok cool!

Answer 4

so its not A

Answer 5

no...but to know whether or not its like b or c or d....make sure to check BOTH equations...

Answer 6

Answer 9

i'll message you:)

Answer 10

check B now....
y < 2x + 4 ...(-5,2)
-5 < 2(2) + 4
-5 < 4 + 4
-5 < 8.......true
y < -2x + 2
-5 < -2(2) + 2
-5 < -4 + 2
-5 < -2...true

Answer 11

so its b
