sketch the feasible region for this system of the inqualities and find the coordinates of each vertex:y greater than or equal to 1;x less than or equal to 2; 1x+2y less than or equal to 6;1x+2y greater than or equal to 2

a) y>/= 1
b) x</=2
2y</= x+6
c) y </= (1/2) x + 3
2 y >/= x +2
d) y >/= (1/2)x + 1
a and d hit at (0,1)
a and b hit at (2,1)
b and c hit at (2,4)
c and d hit at (2,3)
Inside that figure
