Best ResponseYou've already chosen the best response.0Determine a scalar equation for the plane through the points M(1, 2, 3) and N(3 ,2, 1) that is perpendicular to the plane with equation 3x + 2y + 6z + 1 = 0.

Best ResponseYou've already chosen the best response.2the equation of a plane is defined by its "normal vector" if we know the normal vector N, then N dot P = b would be the equation, where P=<x,y,z> represents any point on the plane and b is a scalar.

Best ResponseYou've already chosen the best response.2we denote a vector by either using ai + b j + c k or <a,b,c> either way, it means the same thing. put the tail at <0,0,0> and draw a "line" to point <a,b,c> and then put an arrow head at the end.

Best ResponseYou've already chosen the best response.2there are lots of vectors that point straight up from (0,0,0) (i.e. depends on the length we make the vector) but if we want to point up 1 unit in the zdirection any idea how to write that vector?
