Best ResponseYou've already chosen the best response.0I first assigned the points to P Q and R and then found PQ and PR and then put P+u<PQ>+v<PR> and I got <3+7s+22t,57s+5t,28s+7s> but got it wrong!

Best ResponseYou've already chosen the best response.0I'm assuming you tried <3+7s+22t,57s+5t,28s+7t>and not <3+7s+22t,57s+5t,28s+7s> right?

Best ResponseYou've already chosen the best response.0i did it twice and got it wrong twice

Best ResponseYou've already chosen the best response.0does it specify at all which variables are the free variables (like x and y or x and z)?

Best ResponseYou've already chosen the best response.0hmm well I managed to find a calculator that will give the equation of the plane

jim_thompson5910

Best ResponseYou've already chosen the best response.0that equation is x25y+21z80 = 0 x25y+21z= 80 solve for x: x25y+21z= 80 x = 80+25y21z x = 8025y+21z

Best ResponseYou've already chosen the best response.0so if you let y = s and z = t, then you will get <x, y, z> = <8025y+21z, y, z> <x, y, z> = <8025s+21t, s, t>

Best ResponseYou've already chosen the best response.0what do you mean

Best ResponseYou've already chosen the best response.0as in please show me a way o parameterize this

jim_thompson5910

Best ResponseYou've already chosen the best response.0well you could take the cross product of vectors PQ and PR

jim_thompson5910

Best ResponseYou've already chosen the best response.0that will give you the normal vector to the plane

jim_thompson5910

Best ResponseYou've already chosen the best response.0what do you get when you do the cross product

Best ResponseYou've already chosen the best response.0somewhat close, but that's not correct
