A geometric vector v has x-component 3 and y-component -5.
(a) If we want to represent v in the form v =\overrightarrow{A B} where A = (1, 2) , what are the coordinates of the terminal point B?
(b) If we want to represent v in the form v =\overrightarrow{CD} where D = (5, 7), what are the coordinates of the initial point C?
