Step-by-step explanation:
We need to check whether vectors u and v are equal or not.
If the initial point is
and terminal point is
, then the vector is

Vector v with an initial point of (-5,22) and a terminal point of (20,60).

..... (1)
Vector u with an initial point of (50,120) and a terminal point of (75,158).

.... (2)
