Jeżeli [tex]A=(x_1,y_1)[/tex] i [tex]B=(x_2,y_2)[/tex] to [tex]\overrightarrow{AB}=[x_2-x_1,y_2-y_1][/tex]. Można zatem zapisać, że [tex]B=(x_1+(x_2-x_1),y_1+(y_2-y_1))[/tex].
A więc:
a) [tex]B=(0-3,4+5)=(-3,9)[/tex]
b) [tex]B=(-2+1,5+8)=(-1,13)[/tex]
c) [tex]B=(4+0,-3-6)=(4,-9)[/tex]
d) [tex]B=(\sqrt2+3\sqrt2,2\sqrt2-\sqrt2)=(4\sqrt2,\sqrt2)[/tex]
