Answer:
See bolded below
Step-by-step explanation:
Part I ) To figure the points that lie in the shaded region, consider not the options but all whole points that are multiples of 100 that do so;
[tex]Point 1 ( whole Point ) That Lies in Shaded Region - ( 400, 0 )\\Point 2 - ( 400, 100 )\\Point 3 - ( 400, 200 )\\Point 4 - ( 200, 200 )\\Point 5 - ( 600, 0 )\\Point 6 - ( 300, 0 )\\Point 7 - ( 300, 100 )\\Point 8 - ( 300, 200 )\\Point 9 - ( 500, 0 )\\Point 10 - ( 500, 100 )\\Point 11 - ( 600, 0 )[/tex]
Consider the points at hand;
[tex]A ( 200, 100 ) - \neq Belong to Points Above,\\B ( 300, 100 ) - Belongs to Points Above,\\C ( 400, 100 ) Belongs to Points Above,[/tex]
Thus, Solution ; Point B, C
Part 2 ) Now the Coordinates that meet at the Region's Vertex also belong to that of the points that lie in the shaded region,
[tex]Solution; ( 200, 200 ), ( 300, 200 ), ( 300, 0 ), and, ( 500, 0 )[/tex]
