Answer:

A possible initial point is (1,4) and a possible terminal point is (8,5)

Explanation:

The given vector is
\vec{v}=(7,1).

We can rewrite this vector as:


\vec{v}=\binom{7}{1}

The x-components is 7 and the y-component is 1.

We can choose initial point (a,b) and terminal point (c,d) in the first quadrant such that
c-a=7 and
d-b=1

If a=1, and b= 4, then:


c-1=7 and
d-4=1

This implies that:


c=7+1=8 and
d=1+4=5

Therefore a possible initial point is (1,4) and a possible terminal point is (8,5)
