## anonymous 4 years ago i need work and help, anybody?! Find the minimum and maximum for P = 3x + y. Vertices are (0,0), (4, 0), (3, 4), (0, 10).

then your job is to replace $$x$$ by 0, $$y$$ by 0 and compute then replace $$x$$ by 4, $$y$$ by 0 and compute then replace $$x$$ by 3,$$y$$ by 4 and compute and finally replace $$x$$ by 0, $$y$$ by 10 and compute the biggest is the max, the smallest is the min

for example, the second point $$(4,0)$$ gives $p=3\times 4+0=12$[

im still confused, i dont get this at all
