The answer in the procedure
Step-by-step explanation:
we know that
The solution of the system of inequalities is the shaded area above the solid red line and above the dashed blue line
If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded region
Plot the ordered pairs and verify if represent a solution
Let
A(0,-4),B(-2,4),C(0,5),D(-2,7),E(-4,1),F(-1,1),G(-1.5,3.5)
see the attached figure
A(0,-4) Not a solution of the system
B(-2,4) Solution of the system
C(0,5) Solution of the system
D(-2,7) Solution of the system
E(-4,1) Not a solution of the system
F(-1,1) Not a solution of the system
G(-1.5,3.5) Solution of the system
