Systems of Inequalities
y = x + 4
y = 2x + 5
r + s = -6
r - s = -10
Is (-4,1) a solution to the inequality y<7x+1?
No
y = 3x - 2
y = -x - 2
8a + 5b = 9
2a - 5b = -4
Is (6,1) a solution to 4x+y>=12
(>= means "greater than or equal to")
Yes
y = -3
x = 5
2x + 3y = 6
3x + 5y = 15
Is (0,0) a solution to the system of inequalities?
y>6x
y<-3x
No
y = (1/3)x - 3
2x - y = 8
2a - 4b = 12
-8a + 16b = -48
Is (-4,7) a solution to
-5x + 4x >= 4
y <= 7
Yes
y - 3x = 3
y = 3x - 2
(1/3)x + (1/4)y = 10
(1/3)x - (1/2)y = 4
Give three solutions to the system
2x-6y>18
-2y-11<x
