The vector PQ =(-3,2).Given that the point P is (1,4), find the coordinates of the<br>point Q.

Yakvenalex [24]

Answer:

Q = (- 2, 6 )

Step-by-step explanation:

PQ = q - p ← q and p are the position vectors

Add p to both sides

q = PQ + P = (- 3, 2) + (1, 4) = (- 3 + 1, 2 + 4) = (- 2, 6 ), that is

Q = (- 2, 6 )
