(algorithmic) consider the following linear program: min 2 a + 2 b
s. t.
a + 3 b ≤ 12
3 a + b ≥ 13
a - b = 3 a,
b ≥ 0 choose the correct graph that shows the feasible region.
what are the extreme points of the feasible region?
there are two extreme points: and
find the optimal solution.
the optimal solution is a = , b =

Ab and bc form a right angle at point b. if a= (-3,-1) and b= (4,4) what is the equation of bc?
