Answer:
- solutions: (0, 0) and (3, -1)
- not solutions: (0, -7) and (-7, 2)
Step-by-step explanation:
a.
The problem statement tells you that the doubly-shaded region to the upper right is where the solutions are. You have an infinite number of solution points to choose from in that region.
(0, 0) and (3, -1) are solutions
__
b.
Everywhere else on the graph are points that are not solutions.
(0, -7) and (-7, 2) are not solutions
