Best ResponseYou've already chosen the best response.0the closest point between two spots is a straight line that is perpendicular to it. right?

Best ResponseYou've already chosen the best response.0then lets make a line perpendicular to this one the crosses thru the point (1,0)

Best ResponseYou've already chosen the best response.0then where those lines meet is the nearest point right?

Best ResponseYou've already chosen the best response.0y = 2x; y = (1/2)x is perpendicular to it.

Best ResponseYou've already chosen the best response.00 = (1/2)(1) + b 0 = 1/2 + 1/2 our equation is going to be y = (1/2)x + 1/2

Best ResponseYou've already chosen the best response.0now where do these two equations meet up? y = 2x y = (1/2)x + 1/2 2x = (1/2)x + 1/2 2x + (1/2)x = 1/2 (5/2)x = 1/2   5/2 5/2 x = 1/5 the nearest point is: (1/5 , 2,5)

Best ResponseYou've already chosen the best response.0(1/5 , 2/5) if I can type today :)

Best ResponseYou've already chosen the best response.0y = (1/2)(1/5) + 1/2 y = 1/10 + 5/10 y = 4/10 = 2/5 that chacks out good :)
