Now,
Which is circle with center (1/2,0) radius
take, 
Now,
No, it is not in the solution area for the system.
The point only works in one of the inequalities.
It doesn't work in the inequality: y > -1/2x+ 3
We can put it in to test it:
-7 > (-1/2)3 + 3
-7 > -1.5 + 3
-7 > 1.5 This is a false statement, therefore it is not part of the solution.
