Brainliest ! which of the coordinates are not of th vertices of the feasible region for the system of inequalities y≤4,,x≤5,x+y> 6 a(2,4) b(0,6) c(5,4) d(5,1)

Determine which postulate or theorem can be used to prove that lmn =nmo

Solve the equation for y. -1 = 1/3y + 11. will give 5 stars if answered correctly!
