Question

HELP PLS ! :)Identify each point as a solution of the system (in picture) or not a solution of the system.

(0, 4)

(-2, 4)

(0, 5)

(–2, 7)

(–4, 1)

(–1, 1)

(–1.5, 3.5)

Answer 1

(0, 4) solution

(-2, 4) solution

(0, 5) solution

(-2, 7) solution

(-4, 1) not a solution

(-1, 1) not a solution

(-1.5, 3.5) solution

Explanation:

If a point is in the purple section (the middle of the two lines), than it is a solution.

Answer 2

The answer in the procedure

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
