Question

Name a coordinate that IS a solution to this system. Then, name a coordinate that is not a solution to this system

Answer 1

There are two constraints to this system.
The half-plane that satisfies each constraint (represented by a line) is shaded.
In order to satisfy BOTH constraints, the feasible region must be shaded twice. Points anywhere else will not satisfy at least one constraint, hence are not solutions to the system.
Only points in the feasible region are solutions to the system.

Answer 2

o.o.. You have completely lost me..

Answer 3

Are you doing optimization?

Answer 4

At this point. I'm not even sure.. o.o..
