Step-by-step explanation:
Note arrow indicates direction
vector a goes horizontally right for 1 unit
vector c goes horizontally right for 3 units
So is equivalent to 3a , that is
c = 3a
----------------------------------------
vector b goes up diagonally right for 1 unit
vector d from left to right is equivalent to a add b , that is
d = a + b
-------------------------------------
vector e goes down diagonally right for 1 unit
which is the opposite of vector b
This is denoted by a negative , that is
e = - b
