On the xycoordinate plane, point O is the origin. Suppose vector OE=(3,8) and vector OF=(2,4). What ordered pair represents vector EF?
I tried graphing them but they don't even end up in the same quadrant.
Not sure what to do..

if v(OE) = (3,8), then v(EO) = (3,8)
so v(EF) = v(EO) + v(OF)
= (3,8) + (2,4) = (5,12)
