E (1.5) D(-3) to learn at what distance F point is located, it is necessary to learn distance between points of E and D 3+1.5 = 4.5 - distance between points of E and D as the point of F is at the same distance from a point E, as a point of D, to calculate location of a point of F it is necessary E to add to coordinates of a point distance between points of E and D 1.5+4.5 = 6 - coordinates of a point F 6+3 =9 - distance between points D and F Answer's : 6; 9
